Configure a Primary Path



To configure a primary path with an ERO list, bandwidth, and priority, follow these steps:

  1. In configuration mode, go to the following hierarchy level:

  2. Configure the primary ERO list:

    For example:

  3. Configure the LSP:

    For example:

  4. Configure the primary path:

    For example:

  5. Configure the bandwidth:

    For example:

  6. Configure the priority value:

    For example:

  7. Verify and commit the configuration:

Sample Output

The sample output below illustrates the configuration of the primary path on ingress router R1.


The sample output shows a label-switched path (LSP) with bandwidth and priority applied to only one primary path. The same parameters specified one level up in the hierarchy, at the [edit protocols mpls label-switched-path lsp-path-name] hierarchy level, affect all paths.

The path, via-r2, specifies the complete strict path from the ingress to the egress routers through,, in that order. There cannot be any intermediate routers except the ones specified. However, there can be intermediate routers between and the egress router because the egress router is not specifically listed in the path statement. To prevent intermediate routers before egress, configure the egress router as the last router, with a strict type.
