[j-nsp] MVPN Interoperability Issue

[John Frame]

Actually it is possible to support BGP-MVPNs over a non-P2MP capable  
core by using GRE tunnels.  Each PE would require a Tunnel PIC to  
support both the GRE requirement and the vt interface must be used in  
the routing instance - however if you are using MXs then it is built  
in already on the DPCs.  If Inclusive trees are used, then P2MP  
branches are built statically, but automatic trees can be built if  
using a Selective tree.

Cheers.
