As we are discussing about vrf-vpn, i have one more question
in that area(sorry for asking in this working group).

Is was trying to test virtual-link across the vrf-vpn. Is it
a valid configuration, does virtual-link will come up.

o----AREA2----o----AREA1----o====VPN====o----AREA0
R1            R2            R3          R4

In the above setup, I was trying to bring up virtual link
between R2 & R4.

Thanks,
Mani
