实验：

1.建立骨干的igp

r2:

router eigrp 90

no auto-summary

network 24.1.1.2 0.0.0.0

network 22.1.1.1 0.0.0.0

r4:

router eigrp 90

no auto-summary

network 0.0.0.0

r3:

router eigrp 90

no auto-sumary

network 34.1.1.3 0.0.0.0

network 33.1.1.1

2.骨干内的Mpls

r2:

int f0/0

mpls ip

r4:

int f0/0

mpls ip

int f1/0

mpls ip

r3:

int f1/0

mpls ip

3.pe设备上运行bgp(r2和r3)

r2:

router bgp 65001

neighbor 33.1.1.1 remote 65001

neighbor 33.1.1.1 up lo0

r3:

router bgp 65001

neighbor 22.1.1.1 remote 65001

neighbor 22.1.1.1 up lo0

4.vrf(rd、rt)本端的import和对端的export匹配就可以收路由,vrp是基于接口的.一个接口只能属于一个vrf.一个vrf可以存在多个接口.

r2:

ip vrf ender

rd 23:23

route-target 100:100

show ip vrf detal

r3:

ip vrf ender

rd 23:23

route-target 100:100

int f0/0

ip vrf forwarding ender

ip add 35.1.1.3 255.255.255.0

r2:

int f1/0

ip vrf forwarding ender

ip add 12.1.1.2 255.255.255.0

show ip vrf detail

show ip route vrp ender

ping vrf ender 12.1.1.1

5.mp-bgp vpnv4

r2:

router bgp 65001

address-family vpnv4

neighbor 33.1.1.1 activate

r3:

router bgp 65001

address-family vpnv4

neighbor 22.1.1.1 activate

show bgp all summary

6.pe-ce路由交互和重分布

r2:

router rip

version 2

no auto

address-family ipv4 vrf ender

network 12.0.0.0

r1:

router rip

no au

ver 2

net 12.0.0.0

network 11.0.0.0

show ip rip data

r2:

show ip route vrf ender

r3:

int f0/0

ip ospf 1 area 0

r5:

router ospf 1

network 0.0.0.0 0.0.0.0 area 0

r3:

show ip bgp vpnv4 all

router bgp 65001

address-family ipv4 vrf ender

redistribute ospf 1 match internal external(域间外部)

r2:

router bgp 65001

address-family ipv4 vrf ender

redistribute rip metric 10

router rip

address-family ipv4 vrf ender

redistribute bgp 65001 metric 1

r3:

router ospf 1 vrf ebder

redistribute bgp 65001 metric 1

show mpls forwarding-table

r2:

show ip cef vrf ender 11.1.1.1 detail
