RE: Multicast VPN with MDT

OK..you are the man :)
 
I inserted the given command, and it seems ok now
 
the reason , i guess , was that my router has IBGP peering to its domain neighbors and also EBGP to another AS , for some reason the MDT was picking the EBGP address (which is not the loopback) and use that to intiate  the tunnel , probably because its higher IP address?
 
thanks a lot for the help

Are you sure you have "neighbor x.x.x.x update-source loopback0" in
BGP

If for some reason you can't use update-source command (if PE is an eBGP
neighbor), you can also use "bgp next-hop loopback0" command under
VRF to
force MVPN mGRE tunnel to source from loopback.

Folks
I have a scenario where I am trying to build Multicast VPN using MDT between
PE's .
one of my routers , strangely , is not using the loopback address to
initiate the tunnel (using MDT as explained in documentation should usually
use the BGP peer address , which in my case is the loopback  to
intiate
the tunnel )
I wonder if anyone came across similar problem and explain why it happens?
 
thanks
