[c-nsp] mpls traffic-eng multicast-intact + forwarding-adjacency rpf failure

[Anton Smith]

Hello all,

Am going through a bit of pain at the moment trying to get around TE 
tunnels breaking RPF checks for multicast.

The common wisdom seems to be to use the "mpls traffic-eng 
multicast-intact" command, however this only seems to work for TE 
auto-route.

Is it reasonable to expect that this should work for 
forwarding-adjacency also?

The documentation says that by using the multicast-intact command, that 
it will not consider TE tunnels in the RPF check. It seems to me that 
this should work for forwarding-adjacency as well as auto-route.

This is on 7600s running RSP720s (SRB).

Any hints?

I can provide more details on the design if necessary.

Regards,
Anton
