Hi



There is posibility to make bgp with 2 isp with full feed on CISCO 1812,



256MB RAM, IOS 12.4 (15) T9 ?

It will be max 20/20 Mbit/s, only for 1-1,5 year. Let's there will no nat, no ipsec, only routing, few acl and polices



thanks for practise info



regards Pawel


Probably not full feeds with only 256MB of RAM.

How much free RAM do you have left over after just running normal without BGP?

A full BGP currently is taking up around BGP using 124799048 total bytes of memory

I don't have an 18xx with 256MB of DRAM, so I can't tell. The ones I do have with smaller memory configs run ~60M of free DRAM after boot.

I'd recommend 512MB of DRAM for any BGP full-feed talkers.
