How to determine router handle BGP routing

[Machi Ma]

Hi,

I am working on determine which model of router and RAM size which can handle the BGP routing table.  Did you have any experience how to do a judement. According Ram + CPU .... etc?

Currently I planning to add manage 3 peering with full BGP table for each peering.  Please advise Thx!

Memory requirements depend upon the routing traffic received/sent across all 3 peers, can you specify it?

FYI - starting from 1800 series cisco routers, all routes supported BGP

Best regards,
