Release Information
Statement introduced before Junos OS Release 7.4.
Description
Advertise label-switched paths (LSPs) into IS-IS as point-to-point links. The LSP is advertised in the appropriate IS-IS levels as a point-to-point link and contains a local address and a remote address.
When you advertise LSPs into IS-IS as point-to-point links, the LSPs are used in SPF calculations. The advertisement contains a local address (the from address of the LSP), a remote address (the to address of the LSP), and a metric.
Before a single-hop LSP between a multiaccess link can be announced as up and used in SPF calculations, you must configure an LSP in both directions between two label-switched routers.
Options
name—Identifies the LSP.
level-number—IS-IS level number.
Values: 1 or 2
metric—Metric value.
Range: 1 through 63, or 1 through 16,777,215 (if you have configured wide metrics)
Default: 0 (for lo0), 10 (for all other interfaces)
Required Privilege Level
routing—To view this statement in the configuration.
