Rick you are the man!
I added the command bridge 1 bitswap-layer3-address to r4 and it is on fire!
Awesome!
I very much appreciate everyone's help!
Most of all I appreciate the silver bullet Rick just gave me to kill this
headache!
I love Mentor Technologies! I will recommend it to all of my peers. Please
tell Bruce Caslow I said Hi I was in his class a few weeks ago and he put on
an outstanding ECP class!
