By default, the router accepts multicast packets for each (S,G) pair on an incoming
interface (IIF), which satisfies the RPF check (RPF-IIF). When the router performs RPF
checks, only the interface that first accepts traffic for an (S,G) pair accepts subsequent
traffic for that pair. If traffic stops coming on that interface and starts arriving on another
interface, the router does not accept or forward the traffic.
Some network configurations require the router to accept traffic on any interface. To do
so, you can disable the RPF check on a specified set of (S,G) pairs by issuing the ipv6
multicast-routing disable-rpf-check command.
When you disable RPF checks, the router accepts multicast packets for (S,G) pairs on
any incoming interface. When the router has added the new route to its multicast routing
table, it accepts multicast packets for these pairs on any interface in the virtual router
and forwards them accordingly. Multicast routes established before you issue this
command are not affected.
Use to disable RPF checks for specified (S,G) pairs.
Specify a standard IPv6 access list that defines the (S,G) pairs.
