验证配置
要验证配置，请在 R1 上使用以下 show 命令：
show ip pim vrf red neighbor 命令用于显示 R1 的 PIM 邻居和通过其到达邻居的接口。
R1# show ip pim vrf red neighbor
Neighbor Address Interface Uptime/Expires Ver DR Priority / Mode
---------------------------------------------------------------------------
193.1.1.2 port-channel11 02:34:33/00:01:17 v2 1 / DR S
show ip pim vrf red ssm-range 命令将显示指定的多播地址范围。
R1# show ip pim vrf red ssm-range
Group Address / MaskLen
224.1.1.0 / 24
show ip pim vrf red tib 命令输出将显示 PIM 树信息库 (TIB)。
R1# show ip pim vrf red tib
