Usage Guidelines

Usage Scenario

If an LSP fault is detected, traffic switching is automatically triggered in a tunnel protection group. Alternatively, run the mpls te protect-switch command to trigger traffic switching.

MPLS OAM supports multiple traffic switching modes. These switching modes are prioritized. A newly configured switching mode takes effect only if its priority is higher than that of the existing switching mode.

Prerequisites

Protection tunnel must be configured for the tunnel.
