Solved: some multicast commands

att-sgcops · ‎07-05-2006

we all know RP can be configured to be a RP for a certian multicast group:

ip pim send-rp-announce ethernet0 scope 31 group-list 5

access-list 5 permit 224.0.0.0 15.255.255.255

then what about command"ip pim accept-register"? Is there any differnce?

here is an example:

ip pim accept-register list 105

ip access-list extended 105

permit ip any 224.0.0.0 15.255.255.255 ?

I think the first is used to tell other RP what groups he wants to act as the rp for. It is used by AUTORP to decide who is the RP

The second command is releated to communication between the RP and a end device. I suspect you would have issues if you announced that you were the RP for a range but then did not accept register messages from a end device on that range.
