As far as I can tell, currently defined IP keepalives don't really
cut it.  For example most vendors have a minimum keepalive
interval of 1 second and require 3 lost keepalives before
marking the link as down.  Similarly for OSPF HELLOs.

Is there a special MPLS keepalive defined that allows subsecond
detection of a forwarding failure?  Or is such a beast yet to
be engineered?
