Way too many routes imported in OSPF

[Alarig Le Lay]

Hi,

I’ve set up an OSPF as an IGP to resolve the BGP next-hops on the routes
learned from eBGP sessions.

On one of my border routers (running FreeBSD), the counters are correct:

On the other (running Gentoo), I can’t have so much:

I already tried to restart the protocols, but it doesn’t change
anything.
Any idea?

Thanks,
