[j-nsp] Bug or Not?

[William Jackson]

I have had an issue last weekend with an upstream peer of my transit providers.
They have had a route stuck in the forwarding table for 2 weeks.

The result of this was that they were pointing one of my prefixes to a specific one of my transits, when that transit was down they were black holing my prefix.

They did a BGP clear on their peering with my transit and now it's all wonderful.

They state it is not a bug per se but rather an unexpected event.

I would have thought that this is abnormal behaviour and would have been a bug?

General opinions?
