It's more complicate.

We are connected to IX with RouteServer.
Several times a week, there is a problem on BGP session between RS
(.100) and one of service-routers (.126) providing some prefixes.

The problem is, that sometimes, when this connection is gone (or on
particular provider is gone) I receive prefixes like that:

the problem is, that next hop .100 is route-server, that is NOT a
router, so packets are blackholed..

Interesting is, that on RS, these routes are not in table then !!!

So, I wanted to log all events from .100 and than analyze particular
updates.

Marcin
