Please correct me if I'm wrong, but if the BGP table contains ~500k prefixes, which are then summarized into ~300k routes (RIB), and the FIB contains only the "best path" entries from the RIB, wouldn't the FIB be at or below 300k?
There is nothing to summarize away from global BGP table, if you have number showing less, it's probably counter bug or misinterpretation. Global BGP table, single BGP feed, will take same amount of RIB and FIB. You can see your FIB use in 'show plat hard capa pfc': #show platform hardware capacity pfc Module FIB TCAM usage: Total Used %Used 2 72 bits (IPv4, MPLS, EoM) 884736 712819 81% 144 bits (IP mcast, IPv6) 81920 19235 23% You're probably bit better off than I am :) -- ++ytti
