Re: 3745 and 2620 BGP support

To be more specific, you can accept full BGP routes from a single EBGP peer and a single IBGP peer IF you have 256 MB of SDRAM in the router and you run the correct IOS and feature set.

The c3745 is easy as has accepted 256 MB from inception, the c2620XM will most likely require a ROM and SDRAM upgrade.

The IOS version needs to be the MINIMUM required to run BGP. I.e., don't run IP plus (which includes voice, etc.) or Enterprise anything. Since 12.4(4)T, Advanced Security has supported BGP4. I have had great luck with that feature set on 12.4(4)T or higher on both platforms you mention. For example:

http://www.cisco.com/cgi-bin/Software/Iosplanner/Planner-tool/iosplanner.cgi?get_crypto=&data_from=&hardware_name=3745&software_name=ADVANCED%20SECURITY&release_name=&majorRel=12.4&state=:HW:SW&type=Early%20Deployment

Hopefully that is more helpful...

Good luck!

Re: 3745 and 2620 BGP support

Also one factor to consider is the number of concurrent services you will run along with BGP (full routes) on a 2620 router

I have seen a 2621 router running into High CPU load when you have a lot of concurrent services running.

I would suggest considering an ISR router like 2800 or the 3800 if you plan to take full BGP routes.
