Hey Roque,
This can be accomplished using a third device which will handle the leaking between the two VRFs as follows:
Multicast would include using a third device to "bridge" the two mroutes together:
R2
| |
| |
| vrf A
Source --- R1 vrf A ---- Receiver
or using two RP's (1 in vrf and 1 in global) and MSDP to share the mroutes.
The other option would be to try and use the mVPN Extranet feature on this device alone:
Topology:
-----------
Source ----- VRF A R1 VRF B ----- Receiver
==========
Source: (test router)
