So with this one just now I changed the tunnel ID's and it didn't fix it, I had to recreate the interface on one end, it wasn't showing that it was running but the interface at the other end was showing as running. Weird, but this is something I have seen a number of times now. Router which needed the new interface is running 6.33.3 so not old at all, other end is running 6.22 Any thoughts appreciated.

Some have been running happily for years and then just stop, disable/enable makes no difference. The only way to fix the problem is to either change the tunnel ID or create a whole new interface on each end. Has anybody come across this before ?
