Hi All,
In a single VDC on a Nexus 7706, I am planning to run Fabricpath and MPLS BGP. At the moment these two are running separately,
fabricpath on 5696Q and BGP on 6500 with fabricpath using the overload bit.
set-overload-bit on-startup 60
Now I am wondering if I go ahead and use the same configuration in the same VDC, I may end up creating a blackhole scenario after a reload as BGP will converge and start advertising the routes northbound while fabricpath is still holding back due to the timer. Even if I remove this bit of configuration, the question is after a reload the process that converges first may create a temporary blackhole for a very short while.
Going through the config guide there is a option for "wait-for-bgp" under ISIS config.

But this doesn't apply in fabricpath scenario. Has anyone came across the same situation.
thanks.
