[c-nsp] Cisco 7206VXR/NPE-G1 <--> Cisco WS-C6506 (R7000)

[Jason LeBlanc]

We have a 7206 that is getting lots of input errors and overrun errors  
on the LAN side without CRC errors.  On the WAN side we are getting  
all 3 but on a much smaller scale.  Every couple of weeks the CPU goes  
through the roof but the box has never rebooted.  Can anyone give me a  
detailed breakdown of what I should be looking for here?

The 7200 runs:

BGP for 200Mb/s provider MPLS circuit (not full BGP table)
OSPF
IP CEF
QoS


and you can see the two circuits below....
