Invalid group used for source specific multicast

[forrest.webb]

Is there a difference between the commands ipv6 pim accept-register list <ACL>

VS ipv6 pim ssm range <ACL>? If so, what is it?

Thank you in advance

Hi Forrest,

These two commands serve a completely different purpose and are used in different multicast mode (ASM vs SSM).

"ipv6 pim accept-register list" is configured on the RP and dictates which first hop routers are allowed to send register messages to the RP. It is used in any source multicast (ASM) mode.

"ipv6 pim ssm range" is used to change the default source specific multicast (SSM) group range.
