friends,
I have a scenario where in need to create multiple multipoint GRE tunnels and put them in VRF each for different customers. But the problem i am facing is that i'm giving GRE Source Interface as Loopback of my Router which is in Global Table. It works fine if i have One Tunnel only. But as soon as i create another Tunnel with same Source loopback interface.. Both tunnels goes down. Can someone tell me why is this happening?? If i give different loopback as source interface to each tunnel . All tunnels stays up. But creating so many loopbacks doesn't seem scalable.
BRASI#show run int tunnel 0
