Configure each router with EIGRP routing. The configuration for RTA follows. All routers
have the same basic EIGRP configuration.

Step 2.

RTA(config)# router eigrp 100
RTA(config-router)# network 10.0.0.0
RTA(config-router)# network 172.16.0.0

Task 3: Configure Bandwidth and Automatic Summarization

According to the topology shown in Figure 9-9, RTB and RTC are connected with a 128-
kbps link. Enter the commands on both routers necessary to adjust the default bandwidth
to match the actual speed.

Step 1.

RTB(config)# interface Serial0/0/0
RTB(config-if)# bandwidth 128

RTC(config)# interface Serial0/0/1
RTC(config-if)# bandwidth 128
