Specifying Advanced Settings

 

In this step, you can specify the parameters that define advanced connectivity between sites across the service provider network. The following illustration shows the Advanced page.



To specify advanced settings:

  1. Fill in the fields as indicated in the table.

    Field

    Action

    Include

    Select the Include check box for each advanced setting that you want to include in the service definition.

    Note: If you select any advanced parameters for a service definition, you must also select the Include check box for the Disable tunnel services parameter, and select or clear the Disable tunnel services check box.

    For MX Series devices, if you deploy a VPLS service without selecting the Include check box for Disable tunnel services parameter, the VPLS service is down. As a work around, you can push the configuration to each PE device for the service by running the following command:

    root@test_device# set chassis fpc 0 pic 1 tunnel-services bandwidth 1g

    Disable tunnel services

    Enable or disable tunnel-services to specify that traffic for particular VPLS routing instances be forwarded to specific virtual tunnel (VT) interfaces.

    • To enable tunnel-services, clear the Disable tunnel-services check box.

    • To disable tunnel-services, select the Disable tunnel-services check box (default).

    Disable local-switching

    Enable or disable local switching. In local switching mode, you can terminate multiple Layer 2 circuit pseudowires at a single VPLS mesh group:

    • To enable local switching across the network, clear the Disable local-switching check box.

    • To disable local switching across the network, select the Disable local-switching check box (default).

    fast-reroute-priority

    In the fast-reroute-priority, specify the reroute priority for a VPLS routing instance:

    • HIGH—Set the fast reroute priority for a VPLS routing instance to high. During a fast reroute event, the router repairs next hops for high-priority VPLS routing instances first.

    • MEDIUM—Set the fast reroute priority for a VPLS routing instance to medium. During a fast reroute event, the router repairs next hops for medium-priority VPLS instances after high-priority VPLS routing instances but before low-priority VPLS routing instances.

    • LOW—Set the fast reroute priority for a VPLS routing instance to low, which is the default. During a fast reroute event, the router repairs next hops for low-priority VPLS routing instances last.

    Label block size

    Configure the label block size for VPLS labels by using one of the following values.

    • 2—Allocate the label blocks in increments of 2. Use this setting for a VPLS domain that has only two sites with no future expansion plans.

    • 4—Allocate the label blocks in increments of 4.

    • 8 —Allocate the label blocks in increments of 8. This is the default.

    • 16—Allocate the label blocks in increments of 16. A label block size of 16 enables you to minimize the number of routes in the VPLS domain. Use this setting only if the number of routes is the primary concern.

    Note: This field is unavailable if the Signaling type is LDP and the Auto discovery is enabled.

    Connectivity type

    Select a connection-type to specify when a VPLS connection is taken down, depending on whether the interface for the VPLS routing instance is customer-facing or integrated routing and bridging (IRB):

    • ce—Require that for the VPLS connection to be up, the customer-facing interface for the VPLS routing instance must also be up. If the customer-facing interface fails, the VPLS connection is taken down. This is the default.

    • irb—Allow a VPLS connection to remain up so long as an IRB interface is configured for the VPLS routing instance.

    Note: This field is unavailable if the Signaling type is LDP and the Auto discovery is enabled.

    Editable in Service Order

    By default, each advanced setting that you include in the service definition can be edited in the service order. To prevent the service provisioner from overriding an advanced setting in the service order, clear the Editable in Service Order check box.

  2. Click Finish to save the advanced settings.

    The service definition is complete.
