host1(config)#ipv6 multicast-routing disable-rpf-check denver-list
• Use the no version to restore the default situation, in which the router performs RPF
checks for all (S,G) pairs.
• See ipv6 multicast-routing disable-rpf-check.
Using Unicast Routes for RPF
You can use the ip route-type command to specify that BGP routes should be available
for RPF. Routes available for RPF appear in the multicast view of the routing table.
NOTE: This command functions the same for both IPv4 and IPv6 multicast.
ipv6 route-type
• Use to specify that BGP routes are available only for unicast forwarding, only for
multicast RPF checks, or for both.
• Use the show ipv6 rpf-routes command to view the routes available for RPF.
• By default, BGP routes are available both for unicast forwarding and multicast
reverse-path forwarding checks.
• Example
host1(config)#router bgp
host1(config-router)#ipv6 route-type multicast
• There is no no version.
• See ipv6 route-type.
Defining Permanent IPv6 Multicast Forwarding Entries
An mroute is a multicast traffic flow, a (Source, Group) entry used for forwarding multicast
traffic). By default, forwarding mroutes (with a valid RPF incoming interface) are timed
out if data for them is not received for 210 seconds. However, you can specify an mroute
as permanent by using the ipv6 multicast-routing permanent-mroute command.
ipv6 multicast-routing permanent-mroute
• Use to specify that any newly created mroutes that match the specified access-list
do not time out.
• Using this command does not change existing mroutes.
• Permanent mroutes are removed if a topology change occurs that affects the mroute.
• Permanent mroutes may be removed due to certain protocol actions (for example,
PIM sparse mode switching from shared to shortest path tree).
• Outgoing interface lists of permanent mroutes may change due to protocol actions.
• Example
