Instructions
LDP creates FEC for all destination networks except the route networks obtained by BGP.
�
By default, LDP creates FEC for all destination networks except
the route networks obtained by BGP. However, the number of
networks may be so large that it needs to filter the network for
which FEC need not be created ; or the network administrator
wants to control the creation of FEC , that is, FEC is created
only for the authorized network. This command can realize
such functions.
�
The mpls ldp access-fec for <prefix-access-list> command
can make filter be based on access list. FEC can be created
for all destination addresses allowed by the access list. Only
standard ACL is supported now.
�
The mpls ldp access-fec host-route-only command make
FEC be created only for the destination address with 32-bit
mask. The mpls ldp access-fec host-route-only command
is especially valid in the MPLS/BGP VPN application, because
under such application, LDP only exchanges the label of the
next-hop address (that is, the outer label, the label to the PE)
of VPN routes. The mpls ldp access-fec host-route-only
command can effectively decrease the number of FECs.
�
This command does not collide with the above two policies.
By default, FEC is not created for route networks obtained by
BGP. This command can make FEC also be created for route
networks obtained by BGP.
�
Use the mpls ldp access-fec command to configure policy but
it does not take effect immediately. But The mpls ldp acce
ss-fec force command makes the configuration take effect
immediately.
Tip:
mpls ldp access-fec for <prefix-access-list> and mpls ldp acce
ss-fec host-route-only are mutually exclusive. Thus the network
administrator can choose only one control policy at any time.

Advertises which labels to which neighbors,
basic ACL: 1~99 and 1000~1499
All labels are advertised to all neighbors by default.
The no mpls ldp advertise-labels command without any optional parameter forbids the distribution of any locally assigned
labels. To restore the distribution of all locally assigned labels, use
the mpls ldp advertise-labels command without any optional
parameter. Only standard ACL is supported now.
Up to 99 mpls ldp advertise-labels commands can be executed,
those commands work together to determine how LSR advertises
local labels. In the case that multiple commands are configured,
the following rules should be followed:
1. Each mpls ldp advertise-labels command has a (prefix acl,
peer acl) pair. The access list pair is (none, none) when no optional parameter is specified; and it is (prefix-acl, none) when
the optional parameter is specified but without the keyword
no.
2. There is only one (prefix acl, peer acl) pair “applied to” each
prefix in accordance with the following rules:
i. One (prefix acl, peer acl) pair “applies to” one prefix only
when prefix acl “matches” the prefix, and the match condition is that prefix acl permits the prefix.
ii.
In the case that there is more than one (prefix acl, peer
acl) pair “matching” a prefix; the first (prefix acl, peer acl)
pair “applies to” the prefix (in the sequence configured in
show running-config).
3. When LSR is to advertise a prefix label, it executes the following
operations:
i. Finds the (prefix acl, peer acl) pair “applied to” the prefix.
ii.
In the case that there is no (prefix acl, peer acl) pair
“applied to” the prefix, the label is not advertised to any
neighbor if the no mpls ldp advertise-labels command
is executed; otherwise, the label is advertised to all neighbors.

ZXR10 8900 Series Command Reference (MPLS)
iii. In the case that one (prefix acl, peer acl) pair “applied to”
the prefix, the label is not advertised to any neighbor if
prefix acl denies the prefix.
iv. If prefix acl permits the prefix and there is no peer acl
(namely none), the label is advertised to all neighbors.
v. If prefix acl permits the prefix and there is one peer acl, the
label is advertised to all neighbors permitted by peer acl.
Tip:
This command takes effect immediately after its configuration.
The command can be configured only when the network in stable status. Otherwidse, it could not take effect immediately. Do
not use this command frequently.

no mpls ldp advertise-labels old-style
Defaults
By default, ZXR10 interprets the parameter <prefix-access-list>
after the keyword for according to the rule described in the instruction of the mpls ldp advertise-labels command.
Instructions
Generally, the parameter <prefix-access-list> after the keyword
for conforms to the following rules:
One (prefix acl, peer acl) pair “applies to” a prefix only when the
prefix ACL “matches” the prefix, and the match condition is that
the prefix ACL permits the prefix. This is the general processing
method of access list.
In the early Cisco IOS version, however, the parameter <prefix-ac
cess-list> after the keyword for in the mpls ldp advertise-labels
command is interpreted in a different way as follows:
One (prefix acl, peer acl) pair “applies to” a prefix only when the
prefix ACL “matches” the prefix, and the match condition is that
prefix ACL permits or denies the prefix explicitly. The parameter
prefix ACL with “permit any” or “deny any” matches all prefixes.
The difference between the Cisco early rules and the general processing method of access list is that:
The explicit deny (including deny any) makes the (prefix acl, peer
acl) pair “applied to” the prefix, while the implicit deny does not
take any effect.
If users are used to the early rule, the mpls ldp advertise-labels
old-style command can be used.
Example
This example describes how to configure the router to use the early
rules of Cisco to interpret the parameter <prefix-access-list> after
the keyword for in the mpls ldp advertise-labels command.

The LDP session backoff reestablishment mechanism prevents
two LSRs with incompatible configurations falling into the endless cycle form the establishment of the session to the failure. If the establishment of the session fails because of the

Description
interface
Specifies the interface address as the

<ip-address>
Specifies some address as the transmission

Defaults
By default, ZXR10 takes the router identifier as the transmission
address advertised in the hello message on the frame interface.
Instructions
A TCP connection must be established before an LDP session is
set up between LDP routers, which requires every router know the
peer transmission address (IP address). The LDP discovery mechanism enables the LDP router to advertise its own transmission
address used for establishing TCP connection to the peer.
The advertisement of the transmission address can be explicit (that
is, the transmission address appears in the hello message) or implicit (that is, there is no transmission address appearing in the
hello message). The receiver of hello messages takes the source
IP address of the hello message as the transmission address to set
up TCP connection with the sender.
The mpls ldp discovery transport-address command provides
a way to change the default behavior of the router. If the interface
parameter is used, LDP advertises the IP address of the interface in
the hello message on the interface. If the <ip-address> parameter
is used, the LDP advertises the designated IP address in the hello
message on the interface.
If the configuration of the transmission address is changed during
the precess of the running of the interface, ZXR10 router will delete
the current adjacency relationship on the interface. If there is no
other adjacent relationship maintaining the session maintained by
the current adjacent relationship on the interface (multiple links do
not exist), the session will be closed. The adjacency relationship
(and the session) will be reestablished after a hello message is
received from the peer.

Syntax
Description
for <prefix-access-li

Defaults
By default, LDP allocates popup labels only to the directly connected networks and makes advertisements to the peer LSR.
Instructions
By default, LDP allocates popup labels only to the directly connected networks and makes advertisements to the peer LSR. For
destination networks not directly connected, LDP acquires the idle
label from the label pool as the incoming label and chooses the
label value in the mapping message sent by the next hop of the
route as the outgoing label.
If local router is an edge LSR and the router of nexthop may be
a non-MPLS router, local LSR cannot bind the outgoing label, and
the received label packet be will discarded at the data layer because there is no outgoing label according to the MPLS framework
protocol.
In this case, it is necessary to configure the egress control policy to specify LDP to allocate popup labels to destination networks

flowing out of MPLS network, and make advertises to the upstream
LSR. Thus upstream LSR will forward the traffic from the MPLS network in the form of IP packets (or explicitly popup label packets).
There are two kinds of control policies: based on destination network segment and based on next hop.
1. The egress control policy based on destination networks (mpls
ldp egress for <prefix-access-list>) directly specifies which
destination where local LSR is terminated.
2. The egress control policy based on next hop (mpls ldp egress
nexthop <nexthop-access-list>) specifies which neighbors
are non-MPLS routers so that the traffic of these neighbors
as next hops is the traffic out of MPLS. Local router allocates
popup labels for this traffic.
As long as a route meets either of the two policies, that is, the
destination prefix is permitted by <prefix-access-list> or the next
hop is permitted by <nexthop-access-list> , the LDP will allocate
a popup label to it.
The policy takes effect only on the refreshed FECs after the configuration and does not reallocate labels to the existing FECs. Therefore, it is not recommended to configure this command when the
system is running to avoid inconsistency.
Example
1. The router allocates popup labels to all subnet routes in networks 10.101.0.0/16 and 10.221.0.0/16, and allocates popup
labels to all subnet routes in network 10.222.0.0/16 but not in
10.222.1.0/24.

Example
for <prefix-access-li
st>
Specifies the prefix of the explicit null labels
replacing implicit ones, range: 1~99
to <peer-access-list>
Specifies which neighbors that the explicit
null labels replaces implicit ones is advertised
to, range: 1~99
By default, ZXR10 advertises directly connected networks to all
neighbors by means of implicit null labels.
�
By default, ZXR10 advertises directly connected networks to
all neighbors by means of implicit null labels. The implicit null
label causes the Penultimate Hop Poping (PHP) router to make
PHP. Sometimes, however, it is prohibited for the PHP router to
make such action so that the explicit null label is used in the
outgoing label forwarding packet.
�
The mpls ldp explicit-null command enables the router to
advertise explicit null labels to the neighbors permitted by<pe
er-access-list> and the directly connected networks permitted
by <prefix-access-list>. If the parameter <prefix-access-list>
is not specified in the command, explicit null labels will be advertised to all the directly connected networks; if the parameter <peer-access-list> is not specified in the command, explicit
null labels will be advertised to all neighbors.
�
This command takes effect only to the label advertisement
messages after the configuration. If labels have been advertised before the policy is configured, and the matched networks
and neighbors will not change unless the session is interrupted
and reestablished. Therefore, it is not recommended to configure this command when the system is running to avoid inconsistency.

force
Immediately changes the router identifier
By default, the election rules of LDP router identifier on ZXR10 are
as follows:
1. Firstly, if the mpls ldp router-id command is used to designate the address of an interface as the router identifier, and
28
Confidential and Proprietary Information of ZTE CORPORATION
Chapter 2 MPLS LDP Configuration
the interface has an IP address and it is in the UP state, the
address of the interface will be used as the router identifier.
2. Secondly, if there are loopback interfaces configured with IP
addresses, the maximum IP address of the loopback interface
will serve as the router identifier.
3. Lastly, among the IP addresses of interfaces configured with IP
addresses and in the UP state, the maximum one is selected
as the router identifier.
Instructions
By default, the automatically elected router identifier may be unavailable sometimes, for example, the routing protocol does not
advertise the IP address elected as the router identifier to neighbors. In addition, the router configuration may cause the LPD
router identifier is uncertain, and this invalidates the neighbor’s
control policy.
The mpls ldp router-id command specifies the IP address of an
interface as the router identifier. Note that the interface whose IP
address serves as the router identifier must be in the UP state.
If the optional parameter force is not specified, the router identifier specified by the mpls ldp router-id command will not take
effect until the next router identifier election, and the router identifier takes place in the following cases:
1. LDP restarts.
2. The interface whose IP address serves as the current router ID
is shut down.
3. The interface whose IP address is specified as the current
router ID is not configured with any address.
If the optional parameter force is specified, the effect of the m
pls ldp router-id command depends on the current state of the
specified interface.
1. If the specified interface is in the UP state and its address is not
the current router identifier, the router will change the router
identifier to the specified value, interrupt all the current sessions, release labels learned from the sessions, and terminate
the MPLS forwarding related with the bounding of these labels.
2. If the specified interface is in the DOWN state, the router will
change the router identifier to the specified value once the interface is in the UP state, interrupt all the current sessions,
release labels learned from the sessions, and terminate the
MPLS forwarding related with the bounding of these labels.

This example describes how to specify the IP address of the interface fei_1/1 as the router identifier.

The default peer type is “hub” in VFI configuration mode.
The default peer type is “spoke” in VFI MSPW configuration mode.
Instructions
This command is supported after the platform version 4.6.02. This
command is supported to be configured under vfi mspw configuration mode after the platform version 4.8.20.
The current solution does not support the VPLS automatic discovery mechanism, thus it is necessary to specify all PE addresses in
the same VPLS. This command uses the parameters specified in
the vcid and pwtype commands to establish a pseudo-wire with
the designated PE. The spoke type is used for VPLS hierarchy and
cross-domain.
Example
1. This example describes how to execute the peer command in
VFI configuration mode on the PE.
ZXR10(config)#vfi vfi1

Description
<peer-ip-address>
IP address of peer PE, generally router-id is

<static-pw-name>
the name of static PW
spoke
if spoke option parameter is taken, pw type is
spoke type or hub type.
<tunne-number>
1~64 The tunnel number used in establishing
VPLS. The range is 1~64.
At Vfi configuration mode, the default peer type is hub.
This command is supported after platform version 4.08.22.
The current implementation project doesn't support VPLS automatic finding mechanism. Therefore all PE addresses must be
designated to belong to the same VPLS domain. This command
uses parameters that vcid and pwtypte command designate to establish pw with specific PE. Type spoke is used for VPLS gradation
and cross-domain.
The static PW need to be established first and then bind with peer
. One static PW only can bind one time.

VFI configuration or VFI MSPW configuration
pwtype {ethernet | ethernet-vlan}

ethernet-vlan
Pseudo-wire type: Ethernet or Ethernet-vlan
This command is supported after the platform version 4.6.02.
When a pseudo-wire is established between two PEs, there must
be the negotiation about the type of the pseudo-wire established.
There are two types of the pseudo-wire in VPLS: Ethernet and
Ethernet-vlan. The establishment of a pseudo-wire will fail if the
pseudo-wire types designated by PEs are different.
The two pseudo-wire types correspond to two ways for providing
the VPLS service. If the pseudo-wire type is Ethernet, the VPLS
service is provided in the transparent mode. That is, the PE directly
forwards the user data without checking or processing the vlan
tag of the user data. In this case, the the vlan tag is regarded
as the distinguisher for the user to manage private networks. In
this mode, the input interface offered to the user must be the real
interface.
If the pw type is Ethernet-vlan, the VPLS service is provided in
the rewrite mode. That is, the ingress PE router peels off the vlan
tag in the user data and then forwards the pseudo-wire , while the
egress PE attaches the corresponding vlan tag to the user data
according to the outgoing interface type and then forwards it to
the user.
Example
1. This example describes how to configure the pseudo-wire type
in VFI configuration mode on the PE.
ZXR10(config)#vfi vfi1

Instructions
Use this command to specify a virtual channel identifier (VCID) for
the VPLS instance.
VFI configuration
vcid <vcid>
<vcid>
Different VPLS instances on the same PE
have different virtual channel identifiers
(VCIDs), and VPLS instances with the same
virtual channel identifier (VCID) on different
PEs belong to the same VPLS, range:
1~4294967296
This command is supported after the platform version 4.6.02.
If VPLS instances on two PE routers belong to the same VPLS, a
pseudo wire (PW) must be established between the PEs for communication of these VPLS instances. The pseudo wire (PW) is established to exchange MPLS inner labels which identifies VPLS between two PEs. MPLS inner labels are also named virtual channel
(VC) labels (the pseudo wire (PW) is composed of the VC label
and the MPLS outer label of the LSP). The virtual channel identifier (VCID) configured by this command is used to identify different
VPLS when VC labels are exchanged between PEs.
Example
This example describes how to configure the virtual channel identifier (VCID) as 100 on the PE.

Description
force
The command with this option functions on all
tunnels, including the established and new
tunnels. Without this option, it only functions
on new tunnels
It is implicit-null configuration by default.
This configures RSVP implicit null function. If the function is enabled on a node, as the tail node of the tunnel, this node distributes
a implicit-null label 3 to penultimate hop, or a implicit-null label 0 is
distributed. If there is force parameter after the command, then
the new configuration will function on all tunnels (the established
and new tunnels), or it only functions on the new tunnels.
Restore the default implicit-null configuration with the no. If there
is force parameter after the command, then the new configuration
will function on all tunnels (the established and new tunnels), or
it only functions on the new tunnels.
Example
To configure RSVP implicit null function, execute the following command:

There is not configuration by default.
V4.8.23 and its later versions support this command.
The
command tunnel mpls traffic-eng hot-standby is used to set
backup lsp automatically when master lsp is up.
When lsp, whose value of path-option is <primary-path-option>,
is up, the command tunnel mpls traffic-eng hot-standby
protect <primary-path-option> secondary <secondary-path-op
tion> is used to configure backup lsp according to the path whose
path-option is <secondary-path-option>. When master lsp is up,
path-option is not <primary-path-option>, then do MBB to make
path-option of master lsp as <primary-path-option>, and then
create backup lsp according to the path whose path-option is
<secondary-path-option>.

�
This command id supported after the platform version 4.6.02.
�
To enable the router to support RSVP hello messages, this command must be configured in global configuration mode, and
this command must be enabled on the related interface at the
same time. After this command is enabled, the interface sends
RSVP hello messages to its neighbor at regular time and receives the return message from the neighbor to detect its lifetime state.

Instructions
<num>
Number of sequential Hello acknowledgments
that a node can miss, range: 4~10, default: 4
�
This command is supported after the platform version 4.6.02.
�
The node sends HELLO requests to the neighbor and the neighbor answers HELLO acknowledgments. The node will consider
communication with its neighbor is DOWN when the number
of received acknowledgments does not exceed the configured
value. If a link is very congested or has a very heavy load, it
is recommended to set this number to a value higher than the
default value to ensure that Hello does not falsely declare that
a neighbor is down.
