You can configure zero or more secondary paths. All secondary paths are equal, and the
software tries them in the order that they are listed in the configuration. The software
does not attempt to switch among secondary paths. If the first secondary path in the
configuration is not available, the next one is tried, as so on. To create a set of equal
paths, specify secondary paths without specifying a primary path. If you do not specify
any named paths, or if the path that you specify is empty, the software makes all routing
decisions necessary to reach the egress provider edge switch.
To configure the secondary path:
Create a secondary path for the LSP:
1.
[edit protocols mpls label-switched-path lsp_to_240 to 127.0.0.8]
user@switch# set secondary secondary_path_lsp_to_240 standby
Configure an explicit route for the secondary path by specifying the IP address of the

loopback interface or the switch IP address or hostname of each switch used in the
MPLS tunnel. You can specify the link types as either
statement. This configuration uses the default
TIP: Do not include the ingress provider edge switch in these statements.
List the IP address of the loopback interface or switch address or hostname
of all other switch hops in sequence, ending with the egress provider edge
switch.
