AUTORP PIM: distributing multicast groups between multiple RPs
I've seen the cisco doc about how to configure multiple RPs with AUTORP and to have a different range of multicast groups assigned to each RP, but i don't understand totally how the acl you apply to do so works. This is, to do so you use in the config of the C-RP some like this:
ip pim send-rp-announce Loopback0 scope 15 group-list 33
Where "33" is an ACL, that in my case is:
access-list 33 permit 126.96.36.199 10.255.255.255
Whit this config, i though that this router will be the RP only for the multicast groups that have a first octec like:
This is, i though the acl forces the exact match in the bits that you have put as "0" in the wildcard mask.
However, i'm seing that a multicast group like 188.8.131.52 is accepted too by this c-rp, and in deed the router is elected as RP for this group.
Please, can anyone explain how this acl is interpreted for the system?
