multi-instance enable

Function

The multi-instance enable command configures a conventional IS-IS process as an IS-IS multi-instance process.

The undo multi-instance enable command restores an IS-IS multi-instance process to a conventional IS-IS process.

By default, an IS-IS process is a conventional process, and its IID is 0.

Format

multi-instance enable iid iid-value

undo multi-instance enable [ iid iid-value ]

Parameters

Usage Guidelines

Usage Scenario

Traditionally, only one IS-IS process can be configured on an interface. If multiple IS-IS processes are required, multiple interfaces are needed, and the interface configuration workload is heavy. To reduce the interface count and configuration workload, you can run the multi-instance enable command to configure IS-IS multi-instance processes. A conventional IS-IS process and multiple IS-IS multi-instance processes can be configured on the same interface.

If no IID is manually configured for an IS-IS process, this process is referred to as a conventional IS-IS process; if an IID is manually configured for an IS-IS process, this process is referred to as an IS-IS multi-instance process.

Precautions

This command conflicts with bfdall-interfacesenable and ipv6bfdall-interfacesenable commands.

# Configure conventional IS-IS process 1 as an IS-IS multi-instance process with the IID of 3.
