Release Information

Statement introduced in Junos OS Release 10.

Statement introduced in Junos OS Release 12.3 for the QFX Series.

Description

Enable node-link protection on the specified OSPF interface. Junos OS creates an alternate loop-free path to the primary next hop for all destination routes that traverse a protected interface. This alternate path avoids the primary next-hop router altogether and establishes a path through a different router.

Note: This feature is not supported for the OSPF IPv4 multicast topology or for the OSPFv3 IPv4 multicast or IPv6 multicast topologies because node-link protection creates alternate next-hop paths only for unicast routes.

Required Privilege Level
