as the destination address, and select the best MBGP routing.
If there is only one next-hop for this MBGP routing, you shall check
whether the multicast has been enabled on the outbounding interface
for the next-hop routing.
If not, no MBGP routing could be used for the RPF check;
If so, this MBGP routing could be used for the RPF check and the
corresponding outbounding interface is the RPF interface.
If there is no best routing, no MBGP routing could be used for the RPF
check.
Select the best routing from the multicast static routing table for the RPF
check:
Search for the multicast static routing table based on the IP address for the
source packet as the destination address, and select the best multicast static
routing.
If there is only one next-hop for this multicast static routing, you shall
check whether the multicast has been enabled on the outbounding
interface for the next-hop routing.
If not, no multicast static routing could be used for the RPF check;
If so, you shall check whether there is unicast routing is used for the
RPF check.
If the next-hop for the multicast static routing does not associate
with the unicast protocol number, this multicast static routing could
be used for the RPF check.
If no unicast routing is used for the RPF check, then the multicast
static routing could be used for the RPF check.
If the unicast route could be used for the RPF check, and the
protocol numbers for this unicast routing and associated next-hop
multicast static routing are inconsistent, no multicast static routing
could be used for the RPF check.
If the unicast route could be used for the RPF check, and the
protocol numbers for this unicast routing and associated next-hop
multicast static routing are consistent, the multicast static routing
could be used for the RPF check.
If there are multiple next-hops for this multicast static routing, all
next-hops shall be checked whether the multicast has been enabled on
the outbounding interface for the next-hop routing.
If not, it continues to check the next next-hop routing;
If so, you shall check whether there is unicast routing is used for the
RPF check.
If the next-hop for the multicast static routing does not associate
with the unicast protocol number, this multicast static routing could
be used for the RPF check.
If no unicast routing is used for the RPF check, then the multicast
static routing could be used for the RPF check, and the
correspondent outbounding interface is the RPF interface.
If the unicast route could be used for the RPF check, and the
protocol numbers for this unicast routing and associated next-hop
multicast static routing are inconsistent, it continues to check the
next next-hop routing.
If the unicast route could be used for the RPF check, and the
protocol numbers for this unicast routing and associated next-hop
