Release Information

Statement introduced in Junos OS Release 10.0.


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


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.
