Lab 20: EIGRP Route Leaking

Configure EIGRP on all routers. After the configuration, R1's EIGRP routing table will be like this:

R1#show ip route eigrp
D    192.168.0.0/16 [90/2297856] via 10.0.0.2, 00:00:15, Serial0/0

As you see, 192.168.0.0/16 network is summarized. Let's leak 192.168.0.1/32 into R1's routing table:

access-list 10 permit 192.168.0.1

route-map RM-LEAK permit 10
 match ip address 10

interface Serial0/0
 ip summary-address eigrp 1 192.168.0.0 255.255.0.0 5 leak-map RM-LEAK

As a result, 192.168.0.1/32 is observed in R1's routing table with the summarized network:

R1#show ip route eigrp
     192.168.0.0/32 is subnetted, 1 subnets
D       192.168.0.1 [90/2297856] via 10.0.0.2, 00:01:33, Serial0/0
D    192.168.0.0/16 [90/2297856] via 10.0.0.2, 00:01:02, Serial0/0
