R3(config-if)#
ip address 192.168.3.1 255.255.255.0
Add the 192.168.2.0 and 192.168.3.0 networks to the EIGRP configuration on R3.
Step 2.
R3(config)#
router eigrp 1
R3(config-router)#
network 192.168.2.0
R3(config-router)#
network 192.168.3.0
Verify the new routes.
Step 3.
View the routing table on the R1 router to verify that the new routes are being sent out in
the EIGRP updates sent by R3.

172.16.0.0/16 is variably subnetted, 4 subnets, 3 masks
C 172.16.1.0/24 is directly connected, FastEthernet0/0
D 172.16.2.0/24 [90/3526400] via 192.168.10.6, 00:15:07, Serial0/0/1
C 172.16.3.0/30 is directly connected, Serial0/0/0
D 192.168.1.0/24 [90/2172416] via 192.168.10.6, 00:15:07, Serial0/0/1
D 192.168.2.0/24 [90/2297856] via 192.168.10.6, 00:01:07, Serial0/0/1
D 192.168.3.0/24 [90/2297856] via 192.168.10.6, 00:00:57, Serial0/0/1
192.168.10.0/24 is variably subnetted, 3 subnets, 2 masks
C 192.168.10.4/30 is directly connected, Serial0/0/1
D 192.168.10.8/30 [90/3523840] via 192.168.10.6, 00:15:07,

Apply manual summarization to the outbound interfaces.
Step 4.
The routes to the 192.168.1.0/24, 192.168.2.0/24, and 192.168.3.0/24 networks can be
summarized in the single network 192.168.0.0/22. Use the
ip summary-address eigrp
as-number network-address subnet-mask
command to configure manual summarization on
each of the outbound interfaces connected to EIGRP neighbors:
R3(config)#
interface serial0/0/0
R3(config-if)#
ip summary-address eigrp 1 192.168.0.0 255.255.252.0
R3(config-if)#
interface serial0/0/1
R3(config-if)#
ip summary-address eigrp 1 192.168.0.0 255.255.252.0
Verify the summary route.
Step 5.
View the routing table on the R1 router to verify that the summary route is being sent out
in the EIGRP updates sent by R3.
