Route leaking from global routing table to VRF with static/OSPF

Hi all,

 

I have an ASR router terminating multiple 'guest wireless' VRFs, but the router is using a single ISP connection housed in the Global Routing Table. I require that client subnets within each VRF use the same ISP next hop address within the GRT.

 

I found the command below that lets me leak the default route from the GRT to the GUEST vrf (for example).

 

ASR WAN int - 1.1.1.1

ASR-->ISP next hop - 1.1.1.2

Client Subnet in GUEST VRF - 10.10.10.0/24

 

 

ip route GUEST 0.0.0.0 0.0.0.0 1.1.1.2 global

 

 

When the return traffic from the Internet arrives at the router, how do I route it back to the 10.10.10.0/24 within the GUEST VRF?

 

Can I simply use;

 

ip route 10.10.10.0 255.255.255.0 <GUEST_VRF_next_hop>

What if I was using OSPF to advertise the internal client subnets (within each VRF) to the ASR router?

 

Unfortunately I don't have the ability to test this at the moment, it's still in design stage. I'm looking for the absolute easiest way to implement this. Don't have the ability to run BGP...

 

Any ideas would be greatly appreciated!

 

-Brett
