I have a Cisco 7206 router that is connected with multiple T1s to multiple Internet carriers. We are running BGP 4 to the three carriers. The router is using IOS version 12.1(17). A recent problem brought to my attention the need to optimize the memory of the router. One suggestion was to optimize the memory being used by BGP. It was suggested that I use the article below to help optimize the memory used. By coincidence the memory examples in the article are very close to our current configuration. I'm not too familiar with BGP and it's configuration. I would like to apply an inbound filter list for BGP but I would like to make sure I'm not going to affect our routing. I have included our BGP configuration minus the sensitive information.
I would appreciate any help with configuring an inbound filter list for our router.
Thanks for the reply. I did notice that for the outbound I can use the same list (or number) since all three are using the same expression. The inbound should be individually defined with your suggested lists? I just found a Cisco tech doc on expressions, hope this will help me understand the expressive characters. I will probably need to read up on the route-map command.
