Cisco ISG PBHK and L4 redirection with vrf scenarios

Subscriber and portal may be in different VRF’s.

Subscriber   PBHK İnterface Portal
———-       ——           ——
Global        Global         Global
VRF A         VRF A        VRF A (Portal and PBHK router must be connected on the same device)
VRF A         Global         Global

 

Restriction for the second option;

ISG is not supporting mpls vpn tagged traffic coming from the portal. That means, If the PBHK interface and the portal is in a vrf, portal must be directly connected to the PBHK router.

For the last option. There is no route for the portal in subscriber VRF. There is a need for static route or etc.

ip route vrf VRFA portal_ip_address 255.255.255.255 next_hop_for_portal global

Also we need port bundle command on the backbone,mpls interface.
