If I add 50000 rules to routes by "route add ** " command, I want to know, does this make the route slow ?
Actually, I have 50000 rules and these rules are dynamic, I can add/delete some rules at any time. Is this possible to loadbalance ?
I don't think it will make it slow, since BGP4 on linux (using quagga) does the same thing. If you get the global routing table, it inserts all known routes (couple hundred thousand) in the kernel routing table. But unless you are using a routing protocol (BGP, OSPF, etc), why do you have the need for 50k routes in your routing table?
