[c-nsp] C4500x VSS convergence

Dear experts
I have a strange behaviour to share.

I am testing ISSU and failover of a couple of 4500x configured in VSS.

Basically what I see is that during the failover the active supervisor (or
switc) takes more than 100 seconds to forward ip packets, making routing
convergence is very slow.

SSO and NSF are enabled and if I connect in console to the switch that
becomes active it seems that ip routing table appears only after 100

Has anyone experienced the same issue?
