<R3>display bgp routing-table
  *>   2.2.2.2/32         23.1.1.2        0                     0      12?
 *>   3.3.3.3/32         0.0.0.0         0                     0      ?
 *>   12.0.0.0           23.1.1.2        0                     0      12?
 *>   34.0.0.0           0.0.0.0         0                     0      ?
 *>   192.168.1.0        23.1.1.2        2                     0      12i
 *>   192.168.2.0        0.0.0.0         2                     0      ?

15.验证MSDP对等体建立情况

<R2>display msdp brief
23.1.1.3         Up        01:00:45        34          0          0

16.PC1发送组播信息,查看PIM路由表

<R2>display pim routing-table
 VPN-Instance: public net
 Total 0 (*, G) entry; 1 (S, G) entry

 (192.168.1.1, 224.1.1.1)
     RP: 2.2.2.2 (local)
     Protocol: pim-sm, Flag: SPT 2MSDP ACT 
     UpTime: 00:00:15
     Upstream interface: GigabitEthernet0/0/0
         Upstream neighbor: 12.1.1.1
         RPF prime neighbor: 12.1.1.1
     Downstream interface(s) information:
     Total number of downstreams: 1
         1: GigabitEthernet0/0/1
             Protocol: pim-sm, UpTime: 00:00:15, Expires: 00:03:15
