How to communicate between VRF table and global routing table in a single...

Hello, We need to know that what would be the procedure to have the VRF table and global routing table communicating with each other in a single router. Earlier we were using 2 different routers for this purpose, but now 1 router has to be eliminated. There is no BGP involved for this.

Hi, You could use static routes:- Use the global keyword for the one in the VRF- Specified both the interface and the NH for the one in the GRT. It doesn really scale so should be consider for exception only. Another well known trick is to use an external cable connected to the same router. One port belong to the VRF and the other one to the GRT. You can then use regular static routing or an IGP like OSPF which uses a different process per VRF. Its actually the same thing than using two routers as the idea is still to send the traffic out to receive it on another interface. HTH Laurent.
