[c-nsp] Cisco 7206VXR OSPF

[Jason Berenson]

Joe,

I checked the neighbors too.  I do see the session flap there but again, 
no errors on the ethernet and nothing really obvious as to why it 
flapped.  This just started in the past few days.  I do see some CPU 
spikes to 100% but it doesn't correlate exactly to when the flap occurred.
