**AR5**

### **AS100配置RIP** ###

**AR7**

[AR7]rip
    [AR7-rip-1]net 172.16.0.0
    [AR7-rip-1]net 192.168.6.0

**AR1 **

[AR1]rip
    [AR1-rip-1]net 192.168.6.0
    [AR1-rip-1]net 192.168.5.0

### **AS200配置OSPF** ###

**AR2**

[AR2]ospf
    [AR2-ospf-1]area 0
    [AR2-ospf-1-area-0.0.0.0]net 192.168.5.0 0.0.0.255
    [AR2-ospf-1-area-0.0.0.0]net 192.168.1.0 0.0.0.255

**AR3**

[AR3]ospf
    [AR3-ospf-1]area 0
    [AR3-ospf-1-area-0.0.0.0]net 192.168.1.0 0.0.0.255
    [AR3-ospf-1-area-0.0.0.0]net 192.168.2.0 0.0.0.255

**AR4**

[AR4]ospf
    [AR4-ospf-1]are 0
    [AR4-ospf-1-area-0.0.0.0]net 192.168.2.0 0.0.0.255
    [AR4-ospf-1-area-0.0.0.0]net 192.168.3.0 0.0.0.255

**AR5**

[AR5]ospf 
    [AR5-ospf-1]area 0
    [AR5-ospf-1-area-0.0.0.0]net 192.168.3.0 0.0.0.255

**配置BGP**

**AR1**

[AR1]bgp 100
    [AR1-bgp]peer 192.168.5.1 as-number 200

**AR2**

[AR2]bgp 200
    [AR2-bgp]peer 192.168.5.2 as-number 100

![70 1][]

![70 2][]

查看BGP邻居关系

display bgp peer

此时BGP还没有路由表，因为还没有发布。

![70 3][]

### 引入 ###

**AR1**

[AR1-bgp]import-route rip 1	
    [AR1-bgp]import-route direct

再次查看路由表

![70 4][]

![70 5][]

**AR2 **

[AR2-bgp]import-route direct 	
    [AR2-bgp]import-route ospf 1

![70 6][]

### BGP同步 ###

**AR1**

[AR1]rip	
    [AR1-rip-1]import-route bgp

**AR2**

[AR2]ospf	
    [AR2-ospf-1]import-route bgp

![70 7][]

**AR2或者可以这样操作**

**OSPF中配置添加默认路由**

[AR2]ospf	
    [AR2-ospf-1]undo import-route bgp 
    [AR2-ospf-1]default-route-advertise always
