Usage Guidelines

The total bandwidth of LSPs protected by the bypass tunnel is not more than the bandwidth of the primary tunnel. When multiple bypass tunnels exist, the system selects a single bypass tunnel through the best-fit algorithm.

If global Srefresh or RSVP GR needs to be enabled on the bypass PLR and MP node, configure the MPLS LSR ID of the destination peer FRR MP node as the destination address of the bypass tunnel.

The mpls te bypass-tunnel command cannot be configured simultaneously with the following commands on the same tunnel interface:

mpls te fast-reroute
mpls te backup
mpls te protection tunnel

Example
