Re: Load balancing in routers

Paul's statement about CEF is interesting. It's probably the first public
statement I've ever heard where someone was praising CEF. Usually
discussions about CEF are accompanied by liberal amounts of swearing...




Just my anecdotal 2 cents:



[email protected] 4000M, 4 T1's, load balanced. 5 meg of IP traffic, no filters.



no ip cef - 90% CPU - router on its' knees

ip cef - 40% router alive and kicking



Other than the memery overhead CEF adds to BGP, CEF is painless, and
worthwhile.
