Hi Group,
I also have a similar question..
If we have a senario like this
-----------FR ---R3--eth----Cat3550----eth-----R1--------
Area 0 area 1 area2
R3 is the ABR which connects to the area 0 & area 1.
R1 is the ABR which connects to the area 1 & area 2
Cat 3350 both svi interfaces are in area 1.
So we need to create a virtual link or tunnel to connect the area 2 to the
backbone area.
In this case whcih method is prefered? Tunnel or the Virtual-link
Cheers,
Imal
