B.Peer configuration takes priority, so the final result is that the timer value of peer 1.1.1.2 takes keepalive 10 hold 30

C.The timer takes the minimum value, so the final result is that the timer value of peer 1.1.1.2 takes keepalive10 hold 30

D.The default configuration is timer Keepalive 60 hold180, so pee r1.1.12 has a faster speed of detecting Peer connection failure than the default value

A.The address of the multicast group of SSM is 232.0.0.0~232.255.255.255

B.Statically configure the mapping rules of the SSM address on the IGMP querier, and map the group joining information in the IGMPv1 or IGMPv2 member report to the group leaving information

C.If the IGMP SSM Mapping function is not enabled, neither IGMPv1 nor IGMPv2 support the deployment of multicast in SSM mode

D.IGMP SSM Mapping does not process IGMPv3 report messages.
