[c-nsp] high cpu on VIP in 7507

[Troy Beisigl]

Yes. There are several multilink PPP and multilink frame-relay  
interfaces that are across two VIPs that would not do dCEF, but the  
rest of the traffic in and out of this chassis would/should be. There  
are 5 PA-MC-T3 cards and 2 PA-2T3 cards in the chassis along with this  
interface and a PA-FE-TX . I could submit the entire show int  
switching, but that is a lot of interfaces.
