Abstract:
   The link quality mechanism of the MANET Neighborhood Discovery
   Protocol (NHDP) enables "ignoring" some 1-hop neighbors if the
   measured link quality from that 1-hop neighbor is below an acceptable
   threshold, while still retaining the corresponding link information
   as acquired from HELLO message exchange.  This allows immediate
   reinstatement of the 1-hop neighbor if the link quality later
   improves sufficiently.

   NHDP also collects information about symmetric 2-hop neighbors.
   However it specifies that if a link from a symmetric 1-hop neighbor
   ceases being symmetric, including while "ignored" as described above,
   then corresponding symmetric 2-hop neighbors are removed.  This may
   lead to symmetric 2-hop neighborhood information being permanently
   removed (until further HELLO messages are received) if the link
   quality of a symmetric 1-hop neighbor drops below the acceptable
   threshold, even if only for a moment.

   This specification updates RFC6130 "Mobile Ad Hoc Network (MANET)
   Neighborhood Discovery Protocol (NHDP)", and RFC7181 "The Optimized
   Link State Routing Protocol version 2 (OLSRv2)" to permit, as an
   option, retaining, but ignoring, symmetric 2-hop information when the
   link quality from the corresponding 1-hop neighbor drops below the
   acceptable threshold.  This allows immediate reinstatement of the
   symmetric 2-hop neighbor if the link quality later improves
   sufficiently, thus making the symmetric 2-hop neighborhood more
   "robust".
