What good is it if more-specific bogons are going around in the BGP table ?With OpenBSD 3.6 running pf and bgpd, you can apply a filter rule to BGP updates received from individual peers which updates a pf radix table with the network received:PF and bgpd with local filter table is good when you're expecting those filtered ip routes to change often. But this is not true about bogons
Ok, I guess I did not read original post closely enough. PF is for reinjecting routes that match local rules back into bgp, right? If so I apologize, I though it was talking about taking bgp data and using it to filter local servers.... For looking at active routes and seeing which ones match the rules I personally use "hacked" bird daemon, but it is not ready for public testing... --- William Leibzon, Elan Networks: mailto: william () elan net Anti-Spam and Email Security Research Worksite: http://www.elan.net/~william/emailsecurity/
