Here are my notes as I worked through this lab. Either this lab seemed pretty straight-forward, or I’m getting better!
Requirements:
- The ITA core network is running EIGRP in AS 1
- Implementation:
- router eigrp 1
- no auto-summary
- network <network>
- Verification:
- sh ip protocols
- sh ip eigrp neighbors
- sh ip route
- write memory
- Summarize the loopback interfaces on R2 with the best summary route to the other EIGRP routers
- Implementation:
- interface <interface> (Needs to be done on s1/0 and fa0/0)
- ip summary-address eigrp 1 192.168.1.96 255.255.255.240
- Verification:
- sh ip route on R2
- verify presense of 192.168.1.96/28 summary route
- sh ip eigrp topology all-links on remote router
- verify presence of 192.168.1.96/28 summary route
- write memory
- Loopback 192 on R3 represents a connection to the Internet. Originate a default route into EIGRP from R3
- Implementation:
- ip default-network 192.168.100.0
- Verification:
- sh ip route on R3
- verify 192.168.100.0/24 is a candidate default
- sh ip route on remote router
- verify presence of 192.168.100.0/24 route as candidate default, and that the gateway of last resort is properly populated
- write memory
- The Local Travel Agency router, R4, needs to communicate with the ITA core via OSPF area 0
- Implementation:
- router ospf 1
- network <network> area 0
- Verification:
- sh ip protocols
- sh ip ospf neighbors
- sh ip route ospf
- write memory
- Redistribute OSPF into EIGRP
- Implementation:
- router eigrp 1
- redistribute ospf 1 metric 1500 1500 255 255 1
- Verify:
- sh ip route eigrp on router in ITA core network and verify presence of external EIGRP (D EX) routes for the Local Travel Agency OSPF networks.
- write memory
- Originate a default route into the OSPF process from R3.
- Implementation:
- router ospf 1
- default-information originate always
- Verify:
- sh ip ospf database on R3
- verify presence of Type 5 LSA
- sh ip route ospf on R4
- verify presence of OSPF candidate default external type 2 (O*E2) route
- write memory
- Test connectivity with a TCL script
foreach address {

192.168.1.133
192.168.1.101
192.168.1.105

192.168.100.1
10.1.1.3
10.4.4.4
10.1.1.4
} { ping $address }
Mission complete!
