[c-nsp] multicast MSDP RPF check + private AS issue

[Tantsura, Jeff]

ALL,

I've got following situation:

R1---R2---R3
where R1 is in private AS and also originator of a multicast stream.
R2 and R3 are in different AS's and R2 is removing private AS on it's BGP
session with R3. R2 and R3 are MBGP and MSDP peers
The problem is that MSDP on R3 rejects any multicast route originated by R1.

I think this is happening because of mismatch of AS-PATH information in MSDP
and MBGP(which has private AS replaced by AS of R2).

Any ideas?

Thanks in advance,
Jeff
