. 配置 EIGRP
提问配置网络使用 EIGRP 路由协议
回答
Router1#configure terminal
Enter mands, one per line. End TL/Z.
Router1(config)#interface 0
Router1(config-if)#ip address
Router1(config-if)#exit
Router1(config)#interface point-to-point
Router1(config-subif)#ip address
Router1(config-subif)#exit
Router1(config)#router eigrp 55
Router1(config-router)#network
Router1(config-router)#network
Router1(config-router)#exit
Router1(config)#end
Router1#
注释要确保启用此路由协议的所有路由器配置的 EIGRP 后面的进程号相同,可以使用 show ip eigrp
neighbors 来验证邻居关系。work 来定义发布的网络

. 路由过滤
提问对 EIGRP 学到或者宣告的路由进行过滤
回答
入方向过滤
Router2#configure terminal
Enter mands, one per line. End TL/Z.
Router2(config)#access-list 34 deny
Router2(config)#access-list 34 permit any
Router2(config)#router eigrp 55
Router2(config-router)#distribute-list 34 in
Router2(config-router)#exit
Router2(config)#end
Router2#
出方向过滤
Router1#configure terminal
Enter mands, one per line. End TL/Z.
Router1(config)#access-list 57 permit
Router1(config)#access-list 57 deny any
Router1(config)#router eigrp 55
Router1(config-router)#distribute-list 57 out Serial0/
Router1(config-router)#exit
Router1(config)#end
Router1#
使用 prefix 方式过滤,并且支持 gateway 选项
Router9#configure terminal
Enter mands, one per line. End TL/Z.
Router9(config)#ip prefix-list ALLOWED-PREFIXES permit le 32
Router9(config)#ip prefix-list ALLOWED-PREFIXES deny le 32
Router9(config)#ip prefix-list ALLOWED-NEIGHBORS permit
Router9(config)#ip prefix-list ALLOWED-NEIGHBORS permit
Router9(config)#ip prefix-list ALLOWED-NEIGHBORS deny le 32
Router9(config)#router eigrp 55
Router9(config-router)#distribute-list prefix ALLOWED-PREFIXES gateway ALLOWED-NEIGHBORS in
Router9(config-router)#exit
Router9
