HI Tigers,

First things, are the interfaces in a administratively shut or are the
down|down ?
If admin shut, then all you need to do is do a no shut under each of the
interfaces you want to enable.

If you do that and they are now down|down or where orginally down|down, you
are not even getting a signal from the FR switch.  Start with the basics and
debug your LMI and see if you are getting info back!

Cheers
Troy
