Configuration
2-4
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
multicast static routing are consistent, the multicast static routing
could be used for the RPF check, and the correspondent
outbounding interface is the RPF interface.
If the multicast function is not enabled on the outbounding interface
for all next-hops, no multicast static routing could be used for the
RPF check.
If there is no best routing, no multicast static routing could be used for
the RPF check.
Then, select one routing as the RPF routing from these three best routings.
With the longest-match multicast routing configured, select the
longest-match routing from these three routings. If the masks for these three
routings are the same, select the routing with the highest priority. If the
priority for these routings are the same, select the routing in the sequence of
multicast static routing, MBGP routing and unicast routing.
Without the longest-match multicast routing configured, select the routing
with the highest priority from these three routings. If the priority for these
routings are the same, select the routing in the sequence of multicast static
routing, MBGP routing and unicast routing.
Caution
The effectiveness of MBGP routes recurs on unicast routes rather than
distance. The implementation of current MBGP protocols does not support
equal-cost routes.
The effectiveness of static multicast routes recurs on unicast routes rather than
distance.
If the static unicast route is selected as RPF route, the route must be configured
with the next hop IP address. PIM protocol will select RPF neighbors based on
this next hop IP address. If the static unicast route is not configured with the
next hop IP address, PIM protocol can get RPF neighbors.
2.2 Basic IPv6 Multicast Route Configuration
2.2.1 Enable IPv6 Multicast Route Forwarding
This function enables software to forward multicast packets.
To enable IPv6 multicast route forwarding, run the following command in the
global configuration mode:
Command Function
DES-7200(config)# ipv6
multicast-routing
Enable IPv6 multicast routing.
2.2.2 Enable IPv6 Multicast Route Protocol
PIM-SMv6: refer to PIM-SMv6 configuration for the configuration process.
