Howdy all,
What I'm left thinking is that it would have been great if we'd had a snapshot of our core routing table as it stood hours or even days prior to this event occurring, so that I could compare it with our current "broken" state, so the team could have seen that subnet in the core table and what the next hop was for the prefix. Are there any tools that people are using to track when/what prefixes are added/withdrawn from their routing tables, or to pull the routing table as a whole at regular intervals for storage/comparison purposes? It looks like there's a plugin for NAGIOS, but I'm looking for suggestions on any other tools (commercial, open source, home grown) that we might take a look at. For reference, we are running Cisco as well as Juniper kit.
Periodic table dumps, or even a log of the updates from a quagga router inside your infrastructure could provide this information. That in a nutshell is what routeviews and other collectors do for the dfz routing table.
Feel free to drop me your thoughts off-list. Thank you for any insight ahead of time, -Jason "Feren" Olsen
