hi there... Who would have the time to monitor this if it was a manual process? ;)
Personally, never heard of that but it may happen out there.... We use strict RADB filtering on 95% of our connections. Once a day, we run a copy of IRRPT against a list of peered AS's and update the prefix-lists For transit, we just sanitize the routes (drop private space, drop small subnets etc.) Take care, Paul ________________________________ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Jim McBurnett Sent: Monday, October 29, 2007 2:15 PM To: [EMAIL PROTECTED] Subject: BGP Peering and Prefix filterin Question Hello, Recently I have been told that some ISP's are automatically or maybe manually modifying their BGP inbound prefix listing after a network is not advertised to them for a period of time. So the questions I pose to the group: 1. Is this normal? 2. Can anyone share your policies? 3. Who does it? 4. How often? 5. Is it automagic? Or the dirty work slaved off to the junior engineer in the corner somewhere? a. I know you probably won't trust that junior engineer, but some do.... Anyway just a little research after a small problem a customer recently had.
