Hi,

Yes you do need to check both those things.

How big is your BGP routing table going to be?

For example if you want a copy of the entire BGP routing table from the Internet you are going to need more memory to support it than if it was just a few private BGP routes.

In that case then the router will probably not cope with the load placed upon it.

This is the latest post I remember reading about storing the entire Internet routing table on a router. As stated by one of the posters Giuseppe that's over 320 000 routes and you would need 2G of memory and a fast CPU.

Also, what is your access speed (eg DS3) to your ISP?
