ACL for matching multicast groups for Auto-RP

[sandevsingh]

Hi experts,

I am doing a pim auto-rp multicast deployment, wherein it is required to deny a specific multicast group and permit others.

I am Using the following commands - 

ip access-list standard multicast-acl

deny 239.224.0.19

permit any 

exit

ip pim send-rp-announce loopback 0 scope 32 group-list multicast-acl

Will this work OR i need to use an extended ACL? I am bit confused as by using standard ACL i am only matching source IP, whereas multicast address is always in the destination.

Please advise?

You do not need an extended acl.

All you are doing is specifying the group address to tell the RP which groups to announce it is RP for.
