Using OSPF Routes for Multicast RPF Checks

You can use the show ip ospf database opaque-area command to display information
about traffic engineering opaque LSAs.
For OSPF routes to use established MPLS tunnels as next hops—so that traffic can be
mapped to use these tunnels—you must configure the tunnels with the tunnel mpls
autoroute announce ospf command. See JunosE BGP and MPLS Configuration Guide,
for information about configuring MPLS on a router.
Use to enable SPF calculations to consider the IGP (OSPF) best paths as well as the
MPLS tunnel for forwarding traffic to the MPLS endpoint.
By default, the MPLS tunnel is always selected for traffic to the tunnel endpoint; IGP
paths are not considered. For traffic beyond the endpoint, the tunnel is considered
equally with any other path.
Example
host1(config-router)#mpls spf-use-any-best-path
Use the no version to disable the use of IGP best paths.
See mpls spf-use-any-best-path
Use to enable flooding of MPLS traffic engineering link information into the specified
OSPF area. Flooding is disabled by default.
Example
host1(config-router)#mpls traffic-eng area 0
Use the no version to disable flooding.
See mpls traffic-eng area
Use to specify a stable interface to be used as a router ID for MPLS traffic engineering.
Typically you specify a loopback interface to provide the greatest stability, because
this is flooded to all nodes. The interface acts as the destination node for tunnels
originating at other nodes.
Example
host1(config-router)#mpls traffic-eng router-id loopback 0
Use the no version to remove the interface as a router ID.
See mpls traffic-eng router-id
You can use the ip route-type or ipv6 route-type command to specify whether OSPF
routes are available for only unicast forwarding protocols or only multicast
reverse-path-forwarding (RPF) checks. Routes available for unicast forwarding appear
