[AR2]bgp 200
[AR2-bgp]peer 192.168.5.2 as-number 100
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。
引入
AR1
[AR1-bgp]import-route rip 1
[AR1-bgp]import-route direct 再次查看路由表
AR2
[AR2-bgp]import-route direct
[AR2-bgp]import-route ospf 1
BGP同步
AR1
[AR1]rip
[AR1-rip-1]import-route bgp AR2
[AR2]ospf
[AR2-ospf-1]import-route bgp 
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
