拓扑图

RIP配置

• AR1 AR2 和 AR3 配置RIPv2协议

[AR1]rip 
[AR1-rip-1]version 2
[AR1-rip-1]network 100.0.0.0
[AR1-rip-1]network 12.0.0.0
[AR1-rip-1]network 13.0.0.0

虽然宣告的网段是8/32, 但是最后到达其他路由器的网段是原来的网段

[AR3]display ip routing-table
Route Flags: R - relay, D - download to fib
------------------------------------------------------------------------------
Routing Tables: Public
         Destinations : 15       Routes : 16       

Destination/Mask    Proto   Pre  Cost      Flags NextHop         Interface

       12.1.1.0/30  RIP     100  1           D   23.1.1.1        GigabitEthernet0/0/2
                    RIP     100  1           D   13.1.1.1        GigabitEthernet0/0/1

OSPF配置

[AR1]ospf
[AR1-ospf-1]area 0
[AR1-ospf-1-area-0.0.0.0]network 13.1.1.0 0.0.0.3
[AR1-ospf-1-area-0.0.0.0]network 12.1.1.0 0.0.0.3 
[AR1-ospf-1-area-0.0.0.0]network 100.1.1.0 0.0.0.255 

[AR1]display ip routing-table
Route Flags: R - relay, D - download to fib
------------------------------------------------------------------------------
Routing Tables: Public
         Destinations : 14       Routes : 15       

Destination/Mask    Proto   Pre  Cost      Flags NextHop         Interface
23.1.1.0/30        OSPF    10   2           D   12.1.1.2        GigabitEthernet0/0/1
                   OSPF    10   2           D   13.1.1.2        GigabitEthernet0/0/2

BGP配置

这个表示IBGP

[AR1]bgp 200
[AR1-bgp]peer 45.1.1.1 as-number 200 

这个表示EBGP

[AR1]bgp 200
[AR1-bgp]peer 45.1.1.1 as-number 300 

当进行宣告后, 相连的bgp路由器就会收到这个路由器的宣告信息

[AR1-bgp]network 10.1.1.0 24

BGP路由引入OSPF

[AR3]ospf
[AR3-ospf-1]import-route bgp
[AR3-ospf-1]quit
[AR3]bgp 10
[AR3-bgp]import-route ospf 1
