双向重发布实验
1. 实验拓扑及其要求如上:
2. 实验思路:
(1) 左边、右边拓扑分别启动RIP、OSPF协议完成路由学习
(2) 通过多点双向重发部使得RIP、OSPF协议相互共享路由
(3) R4环回修改借口类型为广播
(4) 通过路由策略,改变cost,干涉路由选路
3. 实验步骤
(1) IP配置:
R1:
int g0/0/0
ip add 12.1.1.1 24
int g0/0/1
ip add 14.1.1.1 24
int l0
ip add 1.1.1.1 24
R2:
int g0/0/0
ip add 12.1.1.2 24
int g0/0/1
ip add 23.1.1.1 24
int l0
ip add 2.2.2.2 24
R3:
int g0/0/0
ip add 23.1.1.2 24
int g0/0/1
ip add 34.1.1.2 24
int l0
ip add 3.3.3.3 24
R4:
int g0/0/0
ip add 34.1.1.1 24
int g0/0/1
ip add 14.1.1.2 24
ip add 4.4.4.4 24
(2)启动动态路由协议:
R1:rip
undo summary
network
12.0.0.0
network
1.0.0.0
network 14.0.0.0
R2:rip
version 2
undo summary
network
12.0.0.0
network

ospf 1
router-id 2.2.2.2
a 0
network
23.1.1.1 0.0.0.0
R3:ospf 1 router-id 3.3.3.3

network
23.1.1.2 0.0.0.0
network
34.1.1.2 0.0.0.0
network
3.3.3.3 0.0.0.0
R4:rip
version 2
undo summary
network
14.0.0.0
ospf 1
router-id 4.4.4.4
a 0
network
34.1.1.1 0.0.0.0
network
4.4.4.4 0.0.0.0
(3)重发部:
R2:ospf 1
import-route
rip
rip
import-route
ospf 1
R4:ospf 1
import-route
rip
rip
import-route
ospf 1
(4) 修改R4环回接口类型:
int l0
ospf network-type broadcast
(5) 路由策略:
R1:ip ip-prefix a permit 23.1.1.0 24
route-policy
ccnp permit node 10
if-match
ip-prefix a
apply
cost-type type-1
apply cost 5
route-policy
ccnp permit node 100
R3:ip ip-prefix 1 permit 12.1.1.0 24
route-policy
hcip permit node 10
if-match
ip-prefix 1
apply
cost-type type-1
apply cost 5
route-policy
hcip permit node 100
