RE: Multicast In Inter-AS MPLS VPN's

Thanks Marko for the reply,
Well yes I am using MDT in the default mode and then the MDT in the data with
the threshold parameters . I am also running MSDP in between the AS but I am
not runing SSM.
The remots ASBR is the msdp peer to one of the internal router in the first
AS.

The point is that when I shut down the ASBR-ASBR link , my traffic flows end
to end and everything runs fine, but the problem comes once the interlink is
brought up, the traffic somehow start to follow the inter links ?
Can you please help in this reagrd.
Thanks
