DMVPN - multiple tunnel interfaces

Unanswered Question
Dec 3rd, 2007

I am trying to configure multiple tunnel interfaces to use one physical

interface on a 7604 router. I am able to get one tu interface to work correctly, however

when I source a second tu interface to the physical interface I get the following nhrp event in the debugs of the

spoke, "9: tunnel addcb failed: reason[failed to create tunnel node] tvlan". Is it

possible to configure multiple tu interfaces to source one physical interface?

I have this problem too.

Run a "clear crypto sa" on the spoke router with NHRP, ISAKMP, and IPSEC debugs running at both ends. When the tunnel reestablishes with data, collect a "sh ip eigrp neighbor" to verify that there is a neighbor relationship for both on the hub and that there are two tunnels in the "sh cry isa sa detail" output. At the same time collect a "sh crypto session" to check the "session status" for each. It should be in an UP-ACTIVE state.
