[c-nsp] link flaps

[Rich Davies]

How big is the circuit that is in between your MUXes?   GRE tunnel adds 24
bytes of packet overhead (GRE packet tax) so if you have a small circuit you
may have bandwidth issues.   You need to think about how many packets you
will be pushing across this circuit x 24 bytes/packet it all adds up
compared to an event driven solution (Cisco EEM).
