Enables fast convergence of devices in the Ethernet Ring Protection (ERP) ring.
Fast convergence is disabled by default.
ERP configuration mode
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.
The following example enables fast convergence in the ERP instance 1.
device# configure terminal device(config)# erp 1 device(config-erp-1) fast-convergence
