Flag Description
authoritative: The mapping was obtained directly from the next-hop router or server.
implicit: The mapping was obtained from an NHRP resolution request or packet.
local: The mapping is for networks that are local to the router.
nat: The remote device supports NHRP Network Address Translation (NAT) extensions.
negative: A mapping could not be obtained for negative caching.
(no socket): IP Security (IPSec) will not set up encryption, because data traffic does not require this tunnel.
registered: The mapping was created in response to an NHRP registration.
router: The mappings for a remote router are marked with the router flag.
unique: The mapping cannot be overwritten by a different NBMA entry with the same IP address.
used: Data packets are being process-switched for the given mapping.
