I have a scenario where i need to use multiple multi-point GRE tunnels and put them in VRF for each customer. The problem i am facing is that for each Tunnel i use Routers loopback in global table as source address. It works fine for one Tunnel. But as soon as i create another tunnel using the same loopback as source. Both tunnels go down. If i use different loopback addresses for each tunnel, all tunnels stays up. Can anyone tell me why i cannot use one loopback as source-address for all tunnels?? creating indiviual loopback for each tunnel doesn't seem scalable.
