Step 2. Configure each router with EIGRP routing. The configuration for RTA follows. All routers<br />

have the same basic EIGRP configuration.<br />

RTA(config)#router eigrp 100<br />

RTA(config-router)#network 10.0.0.0<br />

RTA(config-router)#network 172.16.0.0<br />

Task 3: Configure B<strong>and</strong>width <strong>and</strong> Automatic Summarization<br />

Step 1. According to the topology shown in Figure 3-6, RTB <strong>and</strong> RTC are connected with a 128-kbps<br />

link. Enter the comm<strong>and</strong>s on both routers necessary to adjust the default b<strong>and</strong>width to match<br />

the actual speed.<br />

RTB(config)#interface Serial0/0<br />

RTC(config-if)#b<strong>and</strong>width 128<br />

RTC(config)#interface Serial0/1<br />

RTC(config-if)#b<strong>and</strong>width 128<br />
