Network Learning R&S
Lab 33
Instructions
Please look at the provided diagrams and scan the entire lab before you start. Read
the directions very carefully to make sure you are doing what is being asked of
you.
This
concept
is
very
important
when
you
take
the
CCIE
R&S
lab
exam
administered by Cisco.
Load the initial configuration files for routers. Refer to the diagram for the
interface connections to other routers. The frame relay switch configuration is a
full mesh.
No configuration changes on the backbone routers are required to complete this lab.
Please assume that you do not have access to the backbone routers as that will be
the case in the real lab, also the switches have no initial configuration files and
will be configured from scratch.
Follow the guidelines below unless otherwise specified:
•
Your network should use only the assigned IP address range.
•
Do not change any subnet masks to accomplish a task.
•
There should be no static routes, default routes, default networks,
or any such routes injected by use of a routing protocol, and no
routes leading to Null0 unless expressly permitted.
• You are not allowed to use secondary IP addresses or add Loopbacks that are not
specified.

2.3 Due to the large numbers of VLANS supported it has become necessary
to reduce spanning tree to two instances (not including instance 0).
Even numbered VLANS should be mapped to instance 1 and odd numbered
VLANS should be mapped to instance 2.
2.4 SW4 should be the root for instance 1, while SW3 should be the root
for instance 2.

Interior Gateway Protocols
3.1 Configure RIPv2 as indicated in diagram.

Advertise Loopback 0 on R3 into RIP

Configure R1 so that routes that originate from BB1 have a metric of
10. The 100.3.3.3/32 and 24.234.10.0/24 routes should have a metric
of 1.

Ensure packets between R1 and R3 are authenticated. Use a password
of ‘ccbootcamp’.

Configure a filter on R3 so that only /24 routes with “10.” in the
first octet are accepted. This should be configured in the most
efficient manner possible.
3.2 Configure OSPF as indicated in the diagram

Ensure that every OSPF interface can ping every other OSPF
interface.

Advertise the Loopback interfaces on R1, R4, and R5 into area 0.

Advertise the Loopback interface of R2 into Area 25.

Advertise the loopback interface of R7 into Area 0.

You cannot change the OSPF network type for R1’s Serial 0/0/0
interface.

Ensure R2 receives a single type 3 LSA. Configure R1 and R5 so that
R2 sees R5 as the preferred path. If R5 is not available, then R2
should use R1. R2’s OSPF database should be as follows:OSPF Router with ID (2.2.2.2) (Process ID 1)


Due to poor planning there are separate and disconnected OSPF area
0’s. Ensure that the Separate Area 0’s are connected; a new subnet
24.234.1.0/24 has been allocated for this task.

Configure Area 147 so that no type 4 or type 5 LSA’s are present in
this area. In the event of a failure of R7, SW4 should have full
network connectivity. Test your answer by shutting down fast 0/0 on
R7 and pinging 100.3.3.3.

Configure Area 47 as a stub area.
3.3 Configure EIGRP as indicated in the diagram.

Authenticate the link between R5 and R6 using a password of
‘ccbootcamp’

Advertise R6’s loopback into EIGRP

calculation.

Redistribution
4.1 Mutually Redistribute RIP into OSPF on R1.
4.2 Mutually Redistribute EIGRP and OSPF on Routers R6 and R5.
4.3 After redistribution occurs, ensure that routes advertised from BB2
are still being learned via EIGRP on R6 and R5.
4.4 After redistribution is complete, ensure that R1 is learning
100.3.3.3 via RIP.

BGP
5.1 iBGP

Configure R1, R2 and R3 in A.S 1.

R2 and R3 must have a single iBGP peer.

R4 and R5 are in A.S 2

SW3 and R6 are in A.S 3
5.2 eBGP

Peer R1

Peer R4 to SW3 via eBGP

Peer R5 to R6 via eBGP

There are two Loopback addresses on R6, Loopback 100, and 200.
Advertise these Loopbacks into BGP

Configure BGP so that R1 prefers the path via R4 to reach these
addresses. You may not change the configuration of R1 to achieve
this goal. Ensure that R1 can ping both loopbacks.

that broadcast queue will hold 80 packets, have a maximum byte
transmission rate of 240000 bytes per second, and to have a maximum
packet transmission rate of 160 packets per second
6.2 Configure R1 so that any traffic sourced from R3’s Loopback address
is assigned a precedence value of 5.
6.3 Limit the amount of http traffic incoming on R2’s fast0/0 interface.
Inbound http should be limited to 50000bps. Anything above 50000bps
should be marked as AF11.

R2’s Fast 0/0 interface has been flapping. Configure route dampening on
R5 so that, the half-life is 30 minutes. A route is suppressed when the
penalty reaches 2000, the route will be reused at 1250 and the maximum
suppression is 60 minutes.


Configure IP Multicast on the Serial and Ethernet interfaces on R1, R4
and Sw1 SVI VLAN 14.

Configure PIM version 1, and ensure R4’s Loopback0 is the RP for
multicast groups 224.1.1.1 and 224.1.1.2 only.

Configure R1 F0/0 to join multicast groups 224.1.1.1 and 224.1.1.2.
All multicast routers should be able ping both multicast groups.

Configure R1, R4 and SW1 so that the switchover from the shared to the
