Release Information
Statement introduced in Junos OS Release 14.1.
Description
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 TE-router-ID TLV advertised by a node in the LSP.
Options
exclude [ node-address ]— Specify the list of 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.
node-address— Name
of one or more nodes to be excluded during backup path selection.
preference [ node-address ]— Define an ordered set of nodes to
be preferred. The backup path having the leftmost node is selected.
node-address— Name
of one or more nodes to be preferred in the backup path selection.
