Re: Damn Sham! ***P1*** Help Please

I don't know. Maybe I am missing something here. If I remember SHAM links
correctly, you should be referencing the actual ip address of that
FastEthernet that is in the VRF as the source. I never used the actual
physical interface....interesting. I always used a loopback. I assumed it
had to be a /32. Looks like I have something to lab up to brush up my memory
memory.:-)
Thanks!!!

Paul
