Release Information

Statement introduced in Junos OS Release 15.1.


Define a list of loop-back IP addresses of the adjacent nodes to either prefer or exclude in the backup path selection. The node can be a local (adjacent router) node, remote node, or any other router in the backup path.


The nodes are identified through the route-id advertised by a node in the LSP.


exclude [ node-address ] Specify one or more nodes to be excluded. The backup path that has a router from the list is not selected as the loop-free alternative or backup next hop.
preference [ node-address ] Define an ordered set of one or more nodes to be preferred. The backup path having the leftmost node is selected.
