3.2 路由信息通告

1.network通告方式

[R3]bgp 300
[R3-bgp]network 3.3.3.3 32

2.查看BGP路由信息

[R1]display bgp routing-table 
   i  3.3.3.3/32         23.1.1.3        0          100        0      300i

3.解决 3.3.3.3/32不可达情况

[R2]bgp 12
[R2-bgp]peer 1.1.1.1 next-hop-local
[R2]display bgp routing-table 
 *>i  3.3.3.3/32         2.2.2.2         0          100        0      300i

4.R2在BGP引入OSPF产生路由，R3查看BGP路由

[R2]bgp 12
[R2-bgp]import-route ospf 1
<R3>display bgp routing-table
*>   1.1.1.1/32         23.1.1.2        1                     0      12?
 *>   2.2.2.2/32         23.1.1.2        0                     0      12?
 *>   3.3.3.3/32         0.0.0.0         0                     0      i
 *>   12.0.0.0           23.1.1.2        0                     0      12?
