show ip nhrp

To display Next Hop Resolution Protocol (NHRP) mapping information, use the show ip nhrp command in user EXEC or privileged EXEC mode.

show ip nhrp [dynamic | incomplete | static] [address | interface] [brief | detail] [purge]

Syntax Description

dynamic	(Optional) Displays dynamic (learned) IP-to-nonbroadcast multiaccess address (NBMA) mapping entries. Dynamic NHRP mapping entries are obtained from NHRP resolution/registration exchanges. See Table 23 for types, number ranges, and descriptions.
incomplete	(Optional) Displays information about NHRP mapping entries for which the IP-to-NBMA is not resolved. See Table 23 for types, number ranges, and descriptions.
static	(Optional) Displays static IP-to-NBMA address mapping entries. Static NHRP mapping entries are configured using the ip nhrp map command. See Table 23 for types, number ranges, and descriptions.
address	(Optional) Displays NHRP mapping entries for specified protocol addresses.
interface	(Optional) Displays NHRP mapping entries for the specified interface. See Table 23 for types, number ranges, and descriptions.
brief	(Optional) Displays a short output of the NHRP mapping.
detail	(Optional) Displays detailed information about NHRP mapping.
purge	(Optional) Displays NHRP purge information.

  Type: incomplete, Flags: negative

Table 24 describes the significant fields shown in the displays.

Table 24 show ip nhrp Field Descriptions 

Field	Description
10.1.1.1/8	Target network.
via 10.2.1.1	Next Hop to reach the target network.
Tunnel1	Interface through which the target network is reached.
created 00:00:12	Length of time since the entry was created (hours:minutes:seconds).
expire 01:59:47	Time remaining until the entry expires (hours:minutes:seconds).
never expire	Indicates that static entries never expire.
Type	•dynamic—NHRP mapping is obtained dynamically. The mapping entry is created using information from the NHRP resolution and registrations. •static—NHRP mapping is configured statically. Entries configured by the ip nhrp map command are marked static. •incomplete—The NBMA address is not known for the target network.
NBMA address	Nonbroadcast multiaccess address of the next hop. The address format is appropriate for the type of network being used: ATM, Ethernet, Switched Multimegabit Data Service (SMDS), or multipoint tunnel.
Flags	•authoritative—Indicates that the NHRP information was obtained from the Next Hop Server or router that maintains the NBMA-to-IP address mapping for a particular destination. •implicit—Indicates that the local node learned about the NHRP mapping entries through the source NHRP mapping information from an NHRP resolution request or reply. •local—Indicates NHRP mapping entries that are for networks local to this router (that is, serviced by this router). These flag entries are created when this router answers an NHRP resolution request that has this information and is used to store the tunnel IP address of all the other NHRP nodes to which it has sent this information. If for some reason this router loses access to this local network (that is, it can no longer service this network), it sends an NHRP purge message to all remote NHRP nodes that are listed in the "local" entry (in show ip nhrp detail command output) to tell the remote nodes to clear this information from their NHRP mapping tables. This local mapping entry times out of the local NHRP mapping database at the same time that this information (from the NHRP resolution reply) would time out of the NHRP mapping database on the remote NHRP nodes. •nat—Indicates that the remote node (NHS client) supports the new NHRP NAT extension for dynamic spoke-spoke tunnels to/from spokes behind a NAT router. This marking does not indicate that the spoke (NHS client) is behind a NAT router.
Flags (continued)	•negative—For negative caching, indicates that the requested NBMA mapping could not be obtained. •(no socket)—Indicates that the NHRP mapping entries will not trigger IPsec to set up encryption because data traffic does not need to use this tunnel. Later, if data traffic needs to use this tunnel, the flag will change from a "(no socket)" to a "(socket)" entry and IPsec will be triggered to set up the encryption for this tunnel. Local and implicit NHRP mapping entries are always initially marked as "(no socket)." •registered—Indicates that the mapping entry was created in response to an NHRP registration request. Although registered mapping entries are dynamic entries, they may not be refreshed through the "used" mechanism. Instead, these entries are refreshed by another NHRP registration request with the same Tunnel IP to NBMA IP address mapping. The Next Hop Client (NHC) regularly sends NHRP registration requests to keep these mappings from expiring. •router—Indicates that NHRP mapping entries for a remote router (that is accessing a network or host behind the remote router) are marked with the router flag. •unique—Indicates that an NHRP mapping entry cannot be overwritten by a mapping entry that has the same IP address and a different NBMA address. This prohibition is necessary because the spoke'soutside IP (NBMA) address may change at any time. If the unique flag is set, the spoke has to wait for the mapping entry on the hub to time out before it can register its new (NBMA) mapping. The NHRP registration request packet has the unique flag set by default. •used—Indicates that the mapping entry is being used. The mapping database is checked every 60 seconds. If the used flag is set and more than 120 seconds remain until expire time, the used flag is cleared. If fewer than 120 seconds are left, this mapping entry is refreshed by the transmission of another NHRP resolution request.
