vrf-lite over single Wan Link

[mortaza.rohani]

hello,

I have a multi branch WAN and each branch is connected to HQ via a Single wan link.

now i need to Separate Red and Blue networks in routing table via vrf-lite, but as i've understood, vrf-lite needs at least two physical or logical interfaces.

my question is, can i use vrf-lite using just single Wan link? if not, what is the solution?

Thanks.

Hi,

Some days before, I have tested in my lab as I took 5 interfaces on router as below:

Interface 1:  Branch RED VRF

Interface 2: Branch Green VRF

Interface 3: On WAN (in any of one VRF)

Interface 4:  In RED VRF  (Connect with Interface 5)

Interface 5: IN Green VRF (Connect with Interface 4)

Now configure route to VRF RED to VRF GREEN on interface 4 to 5 and reverse.

Thanks, 

Deepak Kumar
