[AusNOG] Old route from PIPE NSW

[Andrew Jones]

Hi all,
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: 122.100.13.0/24 - it was 44 weeks old and I've lost the 
exact AS path unfortunately, but it began with "4739 7607 7606 7606 
7606".

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.

Is anyone else seeing this route in their tables currently? I'm 
wondering whether it's my router misbehaving and ignoring some 
withdraws?
Thanks,
Andrew
