Hi, I have a FR link which is having 3 point-to-point sub-interfaces. Each sub-interface is mapped with different DLCI and each sub-interface belong to different VRF (VPN). Like sub-interface 1/0.1 -> DLCI 100 -> VRF_A ; sub-interface 1/0.2 -> DLCI 2...

Hi,1. Can we have a pseudowire (AToM) binded to a VRF ( L3MPLS instance) on one MPLS router?2. Can we have VPLS and VRF talking to each other, without using other router..?ALU, JUniper can do it..Rgds,Gaurav Prakash
