When tracking down a routing issue today, I discovered a stale route in the routing table on a peering router of ours, learned from PIPE NSW's route servers: <a href="http://122.100.13.0/24" target="_blank">122.100.13.0/24</a> - it was 44 weeks old and I've lost the exact AS path unfortunately, but it began with "4739 7607 7606 7606 7606".<br>
<br>
When I looked, it did not appear in PIPE NSW's route servers' routing tables as seen from their looking glass. Clearing the sessions to the route-servers has resolved the issue and I'm now reaching that subnet via a /23 route which is being advertised.<br>
<br>
Is anyone else seeing this route in their tables currently? I'm wondering whether it's my router misbehaving and ignoring some withdraws?<br>
Thanks,<br>
Andrew<br>
