Hi
I have a question about BGP & memory requirements: A router is being sent a large number of routes (for example, all the Internet route) but has an input filter only allowing about 10 routes in.
Does the router require enough memory (& cpu) to handle all the routes being sent to it?
Thanks
Peter

Hello Peter,
to handle a full BGP routing table, a minimum of 128MB of RAM is recommended. 10 routes should normaly not be a problem, although other attributes, such as the number of BGP peers, influence the memory utilization as well.
Check this document, it discusses the BGP memory utilization issue:
