Command:

show ip eigrp neighbors


Mode:

Router>


Syntax:

show ip eigrp neighbors [ interface-type| as-number| static]

Syntax Description:

interface-type

(Optional) Interface type.

as-number

(Optional) Autonomous system number.

static

(Optional) Static routes.

 

Command Description:

 

To display the neighbors discovered by Enhanced IGRP (EIGRP), use the show ip eigrp neighborscommand in EXEC mode.

 

Use the show ip eigrp neighborscommand to determine when neighbors become active and inactive. It is also useful for debugging certain types of transport problems.


Example:

The following is sample output from the show ip eigrp neighborscommand:

Router# show ip eigrp neighbors

 show ip eigrp neighbors Field Descriptions

Field

Description

process 77

Autonomous system number specified in the routerconfiguration command.

Address

IP address of the EIGRP peer.

Interface

Interface on which the router is receiving hello packets from the peer.

Holdtime

Length of time (in seconds) that the Cisco IOS software will wait to hear from the peer before declaring it down. If the peer is using the default hold time, this number will be less than 15. If the peer configures a nondefault hold time, the nondefault hold time will be displayed.

Uptime

Elapsed time (in hours:minutes: seconds) since the local router first heard from this neighbor.

Q Count

Number of EIGRP packets (update, query, and reply) that the software is waiting to send.

Seq Num

Sequence number of the last update, query, or reply packet that was received from this neighbor.

SRTT

Smooth round-trip time. This is the number of milliseconds required for an EIGRP packet to be sent to this neighbor and for the local router to receive an acknowledgment of that packet.

RTO

Retransmission timeout (in milliseconds). This is the amount of time the software waits before resending a packet from the retransmission queue to a neighbor.
