fast-convergence

Enables fast convergence of devices in the Ethernet Ring Protection (ERP) ring.

Syntax

fast-convergence
no fast-convergence

Command Default

Fast convergence is disabled by default.

Modes

ERP configuration mode

Usage Guidelines

A convergence time of less than 50-msec can be achieved with 4-device ring topology on 1-RU devices. If the number of nodes in the topology increases, a small linear increase in convergence time occurs accordingly.

The no form of the command disables fast-convergence.

Examples

The following example enables fast convergence in the ERP instance 1.

device# configure terminal
device(config)# erp 1
device(config-erp-1) fast-convergence
