Hi
Yesterday afternoon we experienced an issue where 2 Cisco 7609 (Sup 720 3BXL) routers functioning as PE devices maxed out the CPU for a lengthy period of time. This caused huge BGP instability. The main processes taking the CPU time were either the BGP scanner which I'd expect and LFDp Input Proc.
I can't seem to find a lot of information about this process. Could anyone provide some more detail as to what this process does? The end result to 'fix' the issues was to remove the majority of routes being received by the 7609 turning it more or less into a P device. We do have several other 7609's running with a full BGP table in a identical topology that haven't shown this issue.
Thanks
