查看RIP信息 RouterA#sh ip protocols Routing Protocol is rip Sending updates every 30 seconds, next due in 0 seconds Invalid after 180 seconds, hold down 180, flushed after 240 Outgoing update filter list for all interfaces is Incoming update filter list for all interfaces is Redistributing: rip Default version control: send version 1, receive any version Interface Send Recv Key-chain Ethernet0 1 1 2 Serial2 1 1 2 Routing for Networks: 10.0.0.0 172.16.0.0 Routing Information Sources: Gateway Distance Last Update 10.1.1.2 120 00:00:10 Distance: (default is 120) 172.16.1.1 S2 E0 S3 192.168.1.1 10.1.1.1 10.2.2.2 10.1.1.2 S2 S3 10.2.2.3 172.16.1.0 A B C 192.168.1.0 E0 查看路由表 RouterA#sh ip route Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2 E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, * - candidate default U - per-user static route, o - ODR T - traffic engineered route Gateway of last resort is not set 172.16.0.0/24 is subnetted, 1 subnets C 172.16.1.0 is directly connected, Ethernet0 10.0.0.0/24 is subnetted, 2 subnets R 10.2.2.0 [120/1] via 10.1.1.2, 00:00:07, Serial2 C 10.1.1.0 is directly connected, Serial2 R 192.168.1.0/24 [120/2] via 10.1.1.2, 00:00:07, Serial2 172.16.1.1 S2 E0 S3 192.168.1.1 10.1.1.1 10.2.2.2 10.1.1.2 S2 S3 10.2.2.3 172.16.1.0 A B C 192.168.1.0 E0 RIPv1总结 负载均衡最大6条路径 (默认 = 4) 使用跳数选择路径 每隔30秒进行路由表的更新 有类的，更新包中不含掩码，不支持VLSM 广播更新 不支持认证 RIPv2 与 RIPv1 的区别 是个无类的路由协议 组播（224.0.0.9）路由更新（不用广播） 支持 VLSM（在更新过程中发送掩码） 支持手动汇总 支持 (MD5) 或者 纯文本认证 Router(config)# router rip Starts the RIP routing process, version 1 by default RIPv2 配置命令 Router(config-router)# ver
