实验:配置路由策略 环境:EVE 涉及协议: RIP OSPF EIGRP BGP

首先看下实验需要的拓扑以及IP地址协议

这个颜色很漂亮吧

首先查看接口是否UP IP地址的配置 以及协议是否起来了 R1#show ip interface brief Interface IP-Address OK? Method Status Protocol Ethernet0/0 12.1.1.1 YES manual up up

(1)查看R1当前各协议的邻居状态:

R1#show ip ospf neighbor

R1(config)#router rip R1(config-router)#redi R1(config-router)#redistribute eig R1(config-router)#redistribute eigrp R1(config-router)#redistribute eigrp % Incomplete command.

R1(config-router)#redistribute eigrp ? <1-65535> AS number

R1(config-router)#redistribute eigrp 1 R1(config-router)#do wr

4)查看RIP路由器R3的路由表: R3#show ip route Codes: L - local, C - connected, S - static, 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 i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2 ia - IS-IS inter area, * - candidate default, U - per-user static route o - ODR, P - periodic downloaded static route, H - NHRP, l - LISP 13.0.0.0/8 is variably subnetted, 2 subnets, 2 masks C 13.1.1.0/24 is directly connected, Ethernet0/0 L 13.1.1.3/32 is directly connected, Ethernet0/0 R3#

(5)修改RIP重分布时的默认Metric值:

R1(config-router)# *Apr 11 07:57:15.072: %CDP-4-DUPLEX_MISMATCH: duplex mismatch discovered on Ethernet0/2 (not full duplex), with R5 Ethernet0/0 (full duplex). R1(config-router)#default-metric 10 R1(config-router)#
