multicast-intact.

Hi,

What is the use of multicast-intact command in IOS rtr .

and what is the equivalent command in IOS-XR ?

Usage Guidelines

The mpls traffic-eng multicast-intact command allows PIM to use the native hop-by-hop neighbors even though the unicast routing is using MPLS TE tunnels. The mpls traffic-eng multicast-intact command can only be used with "autoroute announce" functionality.

Examples

The following example shows how to configure PIM and MPLS TE to interoperate:

Router(config-router)# mpls traffic-eng multicast-intact

  • I haven't tried on it, still doing other stuffs but I found one example with explanation here:

    HAPPY STUDY

  • Basically it tells the router to perform the RPF (Reverse Path Forwarding) check against the normal unicast routing table, not the one populated by TE (RSVP). This is to be able to use tunnels only for unicast traffic while keeping the multicast on normal LDP-based LSPs.

    meaning cant use static route for TE if m.cast exists with TE ?
