[c-nsp] link flaps

[Keegan Holley]

Do you manage the MUX's or are they managed by a carrier?  What kind of link
goes between the MUX's?  Protection is usually implemented to prevent this
type of scenario.  Is it possible to just repair the link between the MUX's?
 If not, is it dark fiber?   Can you just buy long range transceivers and
run the ethernet link through the dark fiber?  What protocol is running over
the links?  Can you just lower the timers? Others have suggested BFD, and
IPSLA as options.  Do you control the routers on both sides?  There still
isn't really enough information to suggest a solution.
