Thanks Pavel and Gert. I'm hoping to get in touch with the vendor on Monday and try to get a DFC3BXL sent over.
True, I did not see anything in the log that said about tcam stuff. On our border1, it did show that since I was using a sup2 engine and receiving a full routing table + private peerings. the cpu on border1 was around 30% on the average.
