Is it possible to run the VRF's over subinterfaces.
I want a PE which will be connected to a L2 switch on a dotq trunk and will have two subinterfaces corresponding to 2 customers to forward the traffic out the proper sub interfaces.
The switch is a pure L2 switch and is not possible to run VRF lite on it.
The setup works perfectly when both the customers are terminated on different LAN interface.
Is there any special configuration required to make this work with subinterfaces?

Hi Narayan,
It's not a problem.
Here is an example (PE1):
!
interface FastEthernet0/0
no ip address
no shutdown
!
interface FastEthernet0/0.1
description VRF EFS
encapsulation dot1Q 2
ip vrf forwarding EFS
ip address 144.12.16.1 255.255.255.0
no ip redirects
no ip proxy-arp
no shutdown
!
interface FastEthernet0/0.2
description VRF VoIP
encapsulation dot1Q 3
ip vrf forwarding VoIP
ip address 172.16.2.1 255.255.255.0
no ip redirects
no ip proxy-arp
no shutdown
!
Regads,

Thanks Alexander,
I had tried this on Dynamips simulation but it failed as soon as i created a 2nd subinterface. Will try it once again
I do not have lab equipments to try this out and hence wanted to confirm before i decide on this
