isis topology

Function

The isis topology command associates an IPv4 IS-IS interface with an IPv4 IS-IS topology instance.

The undo isis topology command dissociates an IPv4 IS-IS interface from an IPv4 IS-IS topology instance.

By default, an IPv4 IS-IS interface is associated with an IPv4 IS-IS base topology.

Format

isis topology topology-name

undo isis topology topology-name

Parameters

Parameter	Description	Value
topology-name	Specifies the name of a topology instance.	The value is a string of 1 to 31 case-sensitive characters without spaces. The value must start with a letter (a to z or A to Z, case sensitive) and can contain numbers, hyphens (-), or underlines (_). When double quotation marks are used around the string, spaces are allowed in the string.

Usage Guidelines

Prerequisites

IS-IS has been enabled on the interface using the isis enable command in the interface view.

An IPv4 topology instance has been associated with an IS-IS instance in an IS-IS process using the topology command.

Precautions

If an interface has been bound to a VPN, multi-topology cannot be enabled on the interface.

Example

# Associate GE GigabitEthernet 0/1/0 with the IPv4 topology instance named red.
