You are correct. I changed it as I was in the process of writing the mail to see if filtering even more would cause the number of routes to drop faster. It didn't. Continued dropping at the same slow rate. So I put it back to 23. But the email got parts of each config.

I could clear the bgp tables, but I'm hesitant to do that. Maybe better to just let it drop over time. -----Original Message----- From: Chris Boyd Sent: Wednesday, October 26, 2016 3:57 PM To: [email protected] Subject: Re: [c-nsp] Router memory problem > On Oct 26, 2016, at 2:19 PM, Joseph Mays <[email protected]> wrote: > > I was thinking about using a prefix list to limit the size of the BGP routing > table. Hard to do if you can’t see the config, but I suppose if you are careful you could tftp it in, since you mentioned that’s still working. On the plus side, if you screw up routing with a mistake, you’ll free a lot of memory :-/ —Chris _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp cisco-nsp Info Page - puck.nether.net puck.nether.net cisco-nsp -- list for people using cisco in a NSP (Network service provider) environment About cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/ _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp cisco-nsp Info Page - puck.nether.net puck.nether.net cisco-nsp -- list for people using cisco in a NSP (Network service provider) environment About cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/ _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
