Hi Mohammed,

Thanks for the reply. But I am still unclear how VRF-lite can fix my issue. Let's say my 3750 runs two VRF, single GE link to 2811, and then from 2811, single T1 link to 7600.

Since you can only assign one VRF per interface, how do you transport the two VRFs from the 3750 all the way to the 7600?

I need some kind of multiplex mechanism (similar to multiple PVCs) to transport the VRFs through one physical link. I just don't know what.

Kevin

Ah, yes, it makes sense. Thank you.

Hi Mohammed,

Can you please refer to some document so that I can go through it and understand it in better ways. (CE with multiple VRF-lite and a single connection to PE with any dynamic protocol between them)

Thanks in Anticipation.

Hi,

You can check a previous post for VRF-Lite:

I hope that i've been informative.

Hi,

Suppose following config is on CE

ip vrf cust1

rd 1:1

ip vrf cust2

rd 2:2

int g0/0.1--> sub interface is created on CE for Customer 1

ip vrf forwarding cust1

ip address x.x.x.x

int g0/0.2-->sub interface is created on CE for Customer 1

ip vrf forwarding cust2

ip address y.y.y.y

int g0/1

ip address z.z.z.z --> wan interface which connect to PE

router eigrp 100

network z.z.z.z

I am little bit confused, the eigrp which i will run is on global interface and it will advertise only the global routes as it is

not assigned to any vrf's that is it is between CE and PE so if i want that the

routes which are there in my individual vrf's should also be advertised to PE then how to go with that.

I really apologize for being confused and asking too many questions

Kindly help.

Hi,

No apologize, we are here to help :)

You need to use address families per each VRF

address-family ipv4 vrf customer

network x.x.x.x

no auto-summary

autonomous-system

exit-address-family

!

Then you'll need to redistribute from the VRF EIGRP address family to the main EIGRP process , but this solution is not recommended as the VRF routes will be reachable to each other if not using extensive route filtering, another solution is to run the EIGRP address-family over a tunnel between the 2 CE routers.

Hi,

Thanks a lot once again for explaining it so nicely.
