[c-nsp] Best practice - Core vs Access Router

My guess is that you are sporadically getting flood of glean punts which
are blocking your input buffers causing OSPF/BGP keepalives to be dropped.

I suggest increasing hold-queue input on the interfaces where you see drops
and also to implement glean rate-limit.

For long term, setup ERSPAN for control-plane traffic so if it happens
again in spite of the changes you'll have more data to work with.
