Subject: Re: ip multicast boundary [filter-autorp]
Hi Tim,
the idea is that filter-autorp filters "denied" groups from Auto-RP
messages, hence permitting Auto-RP announces to pass-through
boundary, but cutting out certain unwanted groups.

2006/9/1, Tim Chan <timanji@yahoo.com>: Hi all,
I'm not 100% sure what the "filter-autorp" keyword means.
It's applied after the acl, so does that mean that for those prefixes in the acl
it will also block auto-rp messages for those specific prefixes?
So if I'm trying to block auto-rp messages from being sent out to a backbone
router...are these the same then?
access-list 10 deny 224.0.1.39
access-list 10 deny 224.0.1.40
access-list 10 permit any
!
interface ethernet 0/0
ip multicast boundary 10
vs.
access-list 10 deny 224.0.0.0 15.255.255.255
access-list 10 permit any
!
interface ethernet 0/0
ip multicast boundary 10 filter-autorp
Any comments would be helpful..
