show ip eigrp neighbors

To display information about neighbors discovered by the Enhanced Interior Gateway Routing Protocol (EIGRP), use the show ip eigrp neighbors command.

show ip eigrp [instance-tag] neighbors [detail] [{ethernet slot/port | loopback if_number | port-channel number | vlan vlan-id}] [[vrf {vrf-name | all | default | management}]

Syntax Description

instance-tag

(Optional) Name of the EIGRP instance. The instance tag can be any case-sensitive, alphanumeric string up to 20 characters.

detail

(Optional) Displays detailed EIGRP neighbor information.

ethernet slot/port

(Optional) Specifies the Ethernet interface and the slot number and port number. The slot number is from 1 to 255, and the port number is from 1 to 128.

loopback if_number

(Optional) Specifies the loopback interface. The loopback interface number is from 0 to 1023.

port-channel number

(Optional) Specifies the EtherChannel interface and EtherChannel number. The range is from 1 to 4096.

vlan vlan-id

(Optional) Specifies the VLAN interface. The range is from 1 to 4094.

vrf vrf-name

(Optional) Specifies the name of the virtual routing and forwarding (VRF) instance. The vrf-name argument can be specified as any case-sensitive, alphanumeric string up to 32 characters.

all

(Optional) Specifies all VRF instances.

default

(Optional) Specifies the default VRF.

management

(Optional) Specifies the management VRF.


Command Default

This command displays all neighbors for the default VRF on all interfaces if no VRF or interface is specified.
