RE: OT - Cisco 3825

Holding the BGP table should be no problem if you have max memory. However 3825's best case forwarding is only about 175Mbps, and this is with no features (e.g. NAT, ACLs, etc.). If you need faster aggregate bandwidth than this they you need to go to a higher platform. Obviously something like ASR 1000 is going to be much faster, but of course much more expensive. Here's a quick reference sheet to help you figure out what you really need based on performance: http://www.cisco.com/web/partners/downloads/765/tools/quickreference/routerperformance.pdf

Hi Experts,

As anyone had experience of cisco 3825 being used to connect to an ISP where the global BGP table is being received.

Is the 3825 capable of receiving 300-400 thousand routes? if it has enough DRAM onboard?

Or is this a big NO NO?
