Hi Folks
One thing is different. The neighbor of the config shown previously running IGRP is passive on all interfaces except the ethernet interface which emits one /25. My other concern is that when binding the tunnel to a loopback interface it seems that the tunnel is a lot more reliable and consistent in most aspects. OK I am not talking about redundant paths (reachability issues) through the same router in general. But since a good friend of mine suggested the use of terminating tunnels at the interface level I have been running into instabilities with the GRE tunnel. So I resorted back to using loopbacks and the tunnel encapsulates traffic without a hitch. Could it be that I am missing a KEY here. Bug.
any info needed.

No just the one tunnel is NLSP with ipxwan. The physical interface is Ethernet and running ip only.
thanks bud,

This config is working by the way.
Here is the config. Other router is mirror. I did a snip-snip so you can see the big picture. I also discovered another caveat. But one thing at a time :)

If you need more script let me know....
Thanx Again
