lan-to-lan tunnel issues

[jlloliver]

All,

Having intermittent issues where a l2l tunnel will come up and have traffic in only one direction. l2l tunnels are between a 5510 and one of my 5505's. Restarting the 5505 seems to have no effect.The tunnel us set up so that it can be brought up by either end.

I have re-created the tunnel in question on the 5510 but the only thing that seems to bring it back is to restart the 5510.

Thoughts?

Weird.  Configs?

Things that you can check is if there is overlapping crypto access-list with other tunnels, and also if dynamic crypto map is at the bottom of the crypto map sequence.
