Usage Guidelines

Usage Scenario

FRR protection is configured for networks requiring high reliability. If P2MP TE manual FRR is used, a lot of configurations are needed on the network with complex topology and a great number of links to be protected. In this situation, P2MP TE Auto FRR can be configured.

Unlike P2MP TE manual FRR, P2MP TE Auto FRR automatically creates a bypass tunnel that meets traffic requirements, which simplifies configurations. To configure P2MP TE Auto FRR, run the mpls te p2mp-te auto-frr enable command.

Prerequisites

1.Auto FRR has been globally enabled using the mpls te auto-frr command.

2.P2MP TE has been enabled globally using the mpls te p2mp-te command.
