Lab 19: EIGRP Route Summarization

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

R1#show ip route eigrp
     192.168.0.0/32 is subnetted, 3 subnets
D       192.168.0.1 [90/2297856] via 10.0.0.2, 00:00:04, Serial0/0
D       192.168.0.2 [90/2297856] via 10.0.0.2, 00:00:04, Serial0/0
D       192.168.0.3 [90/2297856] via 10.0.0.2, 00:00:04, Serial0/0

Let's summarize the loopback addresses on R2:

interface Serial0/0
 ip summary-address eigrp 1 192.168.0.0 255.255.0.0 5

As a result, all loopback addresses are summarized as 192.168.0.0/16:

R1#show ip route eigrp
D    192.168.0.0/16 [90/2297856] via 10.0.0.2, 00:00:06, Serial0/0
