show ip eigrp topology

To display the Enhanced Interior Gateway Routing Protocol (EIGRP) topology table, use the show ip eigrp topology command.

show ip eigrp [ instance-tag ] topology [ ip-address/length ] [ active | all-links | detail-links | pending | summary | zero-successors ] [ 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.
ip-address / length
(Optional) IP address in four-part, dotted-decimal notation with a network mask indicated as a slash (/) and number. For example, /8 indicates that the first 8 bits of the mask are 1s, and the corresponding bits of the address are the network address.
active
(Optional) Displays only active entries in the EIGRP topology table.
all-links
(Optional) Displays all entries in the EIGRP topology table.
detail-links
(Optional) Displays detailed information for all entries in the EIGRP topology table.
pending
(Optional) Displays all entries in the EIGRP topology table that are waiting for an update from a neighbor or are waiting to reply to a neighbor.
summary
(Optional) Displays a summary of the EIGRP topology table.
zero-successors
(Optional) Displays available routes in the EIGRP topology table.
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 information for the default VRF if no VRF is specified.

Usage Guidelines

Use the show ip eigrp topology command to determine Diffusing Update Algorithm (DUAL) states and to debug possible DUAL problems.

When you use the show ip eigrp topology command without any keywords or arguments, Cisco NX-OS displays only routes that are feasible successors.

This command requires the LAN Base Services license.

This example shows how to display the EIGRP topology table. The EIGRP metrics for specified internal routes and external routes are displayed.
