[j-nsp] Multicast senders/receivers on the same PE (different VRF) with NG MVPN

Hi,

NG-MVPN extranets are supported since junos 9.5:

http://www.juniper.net/techpubs/en_US/junos11.4/topics/topic-map/mcast-mbgp-extranets.html#jd0e120

As I remember in some corner cases(only two extranet VRFs on the same
router - if my memory serves me right) there is NO need for tunnel hw (VT-
ifls)  -  only  "vrf-table-label" (lsi ifls) should do the trick.

Best Regards,
Krasi
