Release Information

Statement introduced in JUNOS Release 10.0.

Description

Enable link protection on the specified OSPF interface. The JUNOS Software creates a backup loop-free alternate path to the primary next hop for all destination routes that traverse the protected interface.

Note: This feature calculates alternate next hop paths for unicast routes only. Therefore, this statement is not supported with the OSPF IPv4 multicast topology or with the OSPFv3 IPv4 multicast and IPv6 multicast realms.

Required Privilege Level

routing—To view this statement in the configuration.

routing-control—To add this statement to the configuration.
