Lab ssm

全局:
ip muliticast-routing
ip pim ssm default

接口下:
ip pim sparse-mode

如果要在接口下加入igmp v3:
int lo 0
ip add 1.1.1.1 255.255.255.255
ip pim spar
ip igmp join-group 232.1.1.1 source 88.1.1.1
ip igmp version 3

==========================

SSM MAP 的作用是:如果PC不支持IGMPV3,但是需要加入SSM指定的源,需要在最后一跳路由器完成.

ip multicast-routing
ip igmp ssm-map enable
no ip igmp ssm-map query dns
ip pim ssm default
ip igmp ssm-map static 1 88.1.1.1

access-list 1 permit 232.1.1.99

int f0/0
ip add 36.1.1.3 255.255.255.0
ip pim spar
ip igmp version 3(最好打上,兼容)
