that are covered by an NHRP network mapping entry in the table.
Example:
Network mapping:
192.168.13.0/24 via 10.0.0.13, Tunnel0 created 00:02:51, expire 00:07:08
Type: dynamic, Flags: router nat
NBMA address: 172.16.3.1
Incomplete mapping covered by above network mapping
192.168.13.70/32, Tunnel0 created 00:02:51, expire 00:00:13
Type: incomplete, Flags: negative
Cache hits: 61
192.168.13.72/32, Tunnel0 created 00:02:51, expire 00:00:13
Type: incomplete, Flags: negative
Cache hits: 16
