[c-nsp] Forcing BGP to propagate only after route is in the FIB

[Octavio Alvarez]

Hello.

We are noticing our ASR 1002 is propagating BGP-learned routes to its
neighbors after the path is chosen but before the route gets installed
in the FIB.

With the increasing size of the BGP table, this is causing race
conditions that turn into traffic loops during convergence. The router
attracts traffic but returns it back to somebody else because the route
is not yet in the FIB or it is outdated in the FIB.

Is there a way to force the router to wait until a route is installed
all the way in the FIB before having it propagated to the neighbors?

Thanks.
