Giant GRE Networks

Whats the biggest GRE network ever attempted? How many GRE tunnels has someone configured on a router and ran it successfully in an operational setting? Is curent IOS stable when GRE runs at frame-relay-like virtual port densities, say 100 tunnels in a big router?

Re: Giant GRE Networks

We run a network with 800 tunnels, no problems at all. The 7100 series router offer support for 3000 GRE interfaces.
