CNEE 126-Switching & Routing: Student Learning Outcomes:
M. El-Soussi, Fall 2004
Students should be able to successfully:
1. Install, configure, maintain, and document a small to medium size Local Area Network using Virtual Local Area Network
(VLAN) features according to customer specifications.
2. Configure routing protocols to run over Local Area Network (LAN) and Wide Area Network (WAN) using Variable Length
Subnet Mask (VLSM) and Classless Inter-Domain Routing (CIDR) for a given set of specification.
3. Configure and test Dynamic Host Configuration Protocol (DHCP), static Network Address translation and Port Address
Translation (NAT/PAT) over a frame-Relay circuit, using Enhanced Interior Gateway Routing Protocol (EIGRP) for two Wide
Area Network sites.
CASE STUDY RUBRICS (SLO 3, see case study assignment)
Task
Above Standard (+2)
Standard (+1)
Below Standard (0)
Hostname, console, enable
and telnet password
configuration
All routers are assigned
hostnames
Access to a router is
accessible using
password, telnet is
accessible using
password
Successful Ping
One or more passwords are
missing from one or more
routers, a hostname is missing
None of the routers
are configured with
passwords or
hostnames
N/A
Unsuccessful Ping
Frame-relay circuit is
up and running with the
proper DLCIs
Two hosts attached to
the router pick up IP
and gateway
Frame-relay circuit up but
with incorrect DLCIs
Frame-Relay down,
connection failed
Only one host is assigned IP
and Gateway
Hosts are not
picking IP IP
addresses or
Gateway
Interfaces configuration: Ping
all interfaces
Frame-Relay establishedDLCIs mapped
DHCP: Hosts are assigned IP
addresses
Recommendations for Troubleshooting/
Improvement-SAMPLE
Review objective: How to configure hostname,
console ports, telnet and enable sessions on a
router
Review: Interface configuration for Ethernet and
serial ports
Review DLCI to IP mapping
Frame-Relay configuration using InverseARp
Review: DHCP configuration and…
“Show run” should list
excluded IP
configuration
Ping to an outside
interface is successful
NAT table includes a
translation
N/A
Routing protocol: Show ip
route indicates” routes
learned” to reach the public
address such as Internet
EIGRP routes are listed
in the routing table
following show ip route
table
Some EIGRP routes are
missing
from routing table after
issuing show ip route
Clear ip nat trans * and verify
entry deleted using show ip
nat translations Ping an
address not part of NAT
pool- ping should fail
Issue show ip nat
translations-Entry should not
be translated
TOTAL (18)
Ping fails to reach a
non-NAT address
N/A
Entry in the show IP
NAT translation
command is not shown
N/A
DHCP Exclusion test-
NAT/PAT Configuration:
Show ip nat translations after
ping to an outside interface
N/A
“Show run” does
not show excluded
IP configuration
Ping to an outside
interface is not
successful
NAT table does not
include a translation
EIGRP routes are
missing
from routing table
after issuing show
ip route
Ping reaches a nonNAT address
Review DHCP configuration
Entry in the show
IP NAT translation
is shown
Review: NAT/PAT translation configuration
Review NAT/PAT translation configuration
Review: Configuring EIGRP protocol using
network statements and process ID
Review: NAT/PAT translation configuration
