[j-nsp] Troubleshooting BGP

[Stefan Fouant]

I see your point here, but we weren't talking about readvertising an
IGP route into BGP, but rather how to get the inactive BGP route

handy, but in general I've seen it bring about many more operational
issues than it tends to resolve...

Just my $.02.
