3825 Router

[PAUL CHEN]

Hi,

Will a 3825 with 1GB of memory be capable of BGP peering and have sufficient memory to store an entire internet routing table ?

Any help appreciated.

Thanks,

Paul

I would say 1GB is plenty. The amount of memory required also depends on what other processes are running/configured on the router.

According to Cisco, you should atleast have 128 MB of RAM to just hold full Internet routing table. Number of routes in the Internet are increasing day by day. Currently, I think the numbers are in the range of 120000+ routes. This is based on the stats provided in this link

You can read more about memory requirements at RFC 1770.

Hope that helps!
