eigrp协议配置命令篇一
我们在接口配置过程中，帧中继的dlci号和ip映射时也没有配置broadcast 参数，这类问题该如何解决?下面小编给你带来的内容回答以上疑问。
r1(config)#router eigrp 100
r1(config-router)#no auto-summary //关闭自动汇总
r1(config-router)#net 192.168.1.0 //宣告路由条目
r1(config-router)#end
r2(config)#router eigrp 100
r2(config-router)#no auto-summary
r2(config-router)#net 192.168.1.0
r2(config-router)#net 10.1.0.0 0.0.255.255 //宣告路由条目
r2(config-router)#end
r3(config)#router eigrp 100
r3(config-router)#no auto-summary
r3(config-router)#net 192.168.1.0
r3(config-router)#net 172.16.0.0 0.0.255.255
r3(config-router)#end
r1#show ip eigrp neighbors //查看eigrp 邻居表，发现并没有邻居
ip-eigrp neighbors for process 100
r1#show ip eigrp topology //查看eigrp 拓扑表，并没有学习到任何的路由
ip-eigrp topology table for as(100)/id(192.168.1.1)
codes: p – passive, a – active, u – update, q – query, r – reply,
r – reply status, s – sia status
p 192.168.1.0/24, 1 successors, fd is 2169856
via connected, serial0/0
因为帧中继默认为nbma 模式，也就是非广播的多路访问模式，它会阻止广播数据和组播数据，我们在接口配置过程中，帧中继的dlci 号和ip 映射时也没有配置broadcast 参数，而eigrp 路由协议通过组播地址224.0.0.10 来发送相应的路由信息(比如hello、update 等数据包)，所以r1 并没有发现任何的邻居路由器。
为了能让eigrp的路由信息通过帧中继传播，在没有配置broadcast 参数的情况下，我们可以通过单播的形式来发送eigrp 数据包，我们对以上的配置进行改进：
r1(config)#router eigrp 100
r1(config-router)#neighbor 192.168.1.2 serial 0/0 //手工指定邻居，实现单播方式
r1(config-router)#neighbor 192.168.1.3 serial 0/0
r1(config-router)#end
r2(config)#router eigrp 100
r2(config-router)#neighbor 192.168.1.1 serial 0/0 //手工指定邻居，实现单播方式
r2(config-router)#end
r3(config)#router eigrp 100
r3(config-router)#neighbor 192.168.1.1 serial 0/0 //手工指定邻居，实现单播方式
r3(config-router)#end

查看r2 的路由表：
r2#show ip route
codes: c – connected, s – static, r – rip, m – mobile, b – bgp
d – eigrp, ex – eigrp external, o – ospf, ia – ospf inter area

c 10.1.1.0 is directly connected, loopback1
c 10.1.0.0 is directly connected, loopback0
c 192.168.1.0/24 is directly connected, serial0/0
发现r2 并没有学习到r3 的172.16.0.0 网络， r1 通过s0/0 接口学习到r3 宣告的172.16.0.0网络，因为r1 s0/0 接口的水平分割机制导致r1 不会再由这个接口s0/0 发布出去，所以r2无法学习到r3 宣告的网络，同理，r3 也无法学习到r2 宣告的网络。
对帧中继配置进行修正，使用broadcast 参数：
r1(config)#router eigrp 100
r1(config-router)#no neighbor 192.168.1.2 s0/0 //取消手工指定邻居
*mar 1 00:42:29.807: %dual-5-nbrchange: ip-eigrp(0) 100: neighbor 192.168.1.2 (serial0/0) is down:
r1(config-router)#no neighbor 192.168.1.3 s0/0
*mar 1 00:42:32.623: %dual-5-nbrchange: ip-eigrp(0) 100: neighbor 192.168.1.3 (serial0/0) is down:
r1(config-router)#exit
r1(config)#int s0/0
r1(config-if)#no fram map ip 192.168.1.2 102 //取消之前不带broadcast 参数的静态映射
r1(config-if)#no fram map ip 192.168.1.3 103
r1(config-if)#frame map ip 192.168.1.2 102 broadcast
r1(config-if)#frame map ip 192.168.1.3 103 broadcast
r1(config-if)#end
r2(config)#router eigrp 100
r2(config-router)#no neighbor 192.168.1.1 serial0/0
r2(config-router)#int s0/0
r2(config-if)#no frame-relay map ip 192.168.1.1 201
r2(config-if)# frame-relay map ip 192.168.1.1 201 broadcast
r3(config)#router eigrp 100
r3(config-router)#no neighbor 192.168.1.1 serial0/0
r3(config-router)#int s0/0
r3(config-if)#no
*mar 1 00:47:58.943: %dual-5-nbrchange: ip-eigrp(0) 100: neighbor 192.168.1.1 (serial0/0) is up: new adjacency
r3(config-if)#no frame-relay map ip 192.168.1.1 301
r3(config-if)#frame-relay map ip 192.168.1.1 301 broadcast
r3(config-if)#end
可以看到添加了broadcast 后，帧中继可以正常的.传递组播数据了，r1 就可以和r2 和r3 建立邻居关系并正常学习到路由。

d 10.1.0.0 [90/2297856] via 192.168.1.2, 00:02:46, serial0/0
查看r3 的路由表，发现r3 并没有学习到r2 的网络，这是因为r1 默认情况下接口有水平。
r3#show ip route

d – eigrp, ex – eigrp external, o – ospf, ia – ospf inter area

c 172.16.3.0 is directly connected, loopback3
c 192.168.1.0/24 is directly connected, serial0/0
将r1 接口的水平分割关闭：
r1(config)#interface serial 0/0
r1(config-if)#no ip split-horizon eigrp 100
r1(config-if)#end
当r1 的水平分割关闭后，eigrp 进程会出现相应提示：
*mar 1 00:52:25.055: %dual-5-nbrchange: ip-eigrp(0) 100: neighbor 192.168.1.3 (serial0/0) is resync: split horizon changed

查看r1 接口s0/0 的情况：
r1#show ip int s0/0 | include split
split horizon is disabled
r2#show ip route eigrp 100
172.16.0.0/24 is subnetted, 4 subnets
d 172.16.0.0 [90/2809856] via 192.168.1.1, 00:08:03, serial0/0
d 172.16.1.0 [90/2809856] via 192.168.1.1, 00:08:03, serial0/0
d 172.16.2.0 [90/2809856] via 192.168.1.1, 00:08:03, serial0/0
d 172.16.3.0 [90/2809856] via 192.168.1.1, 00:08:03, serial0/0
虽然r2 路由表中有172.16.2.0/24 网络，但r2 并没有ping 通，这是什么原因?
因为r3 的串行口帧中继配置时，只做了ip 192.168.1.1 和dlci 号的对应，没有做ip 192。168.1.2 和dlci 号的映射，所以r2 ping 172.16.2.1 时，采用的源地址为192.168.1.2，通过路由表发现目的地址172.16.2.1 具有符合的条目，转发接口为192.168.1.1，于是由r1 转发到r3，r3 在回包过程时，源地址为172.16.2.1，而目标地址为192.168.1.2，但它不知道这个地址怎么转发于是就丢弃。
