    Add Access Diversity Parameters for EVPN-VPWS Site Network Access

    Expand Access Diversity and add the access diversity parameters.

    A network administrator can group the connections from a site to the service provider network, assign group ID to each connection group, and apply certain constraints to all the connections included in a group. A constraint is expressed in relation to another set of connections (target set). For example, a connection X in a group with group ID G1 must be "PE-diverse" (constraint type) from connections in a target group with group ID G2. The site network access that you are configuring might use the same or different group ID than the target network accesses. You can assign one or more group IDs for a connection, specify constraint types, and select the target group ID that the constraint must be applied to, in the Access Diversity section.

    To assign group IDs to a connection and apply constraints to target group IDs:

    1. Expand Access Diversity on the Add Connection page.

    2. Add IDs of groups that the connection is to be a part of:

      1. Expand Groups and click the add (+) icon.

        The Group page appears.

      2. Enter one or more IDs of the groups to which the connection must be assigned and click OK.

        The group ID entries are listed in the Group ID table.

      3. (Optional) Use the edit or delete options above the Group table to edit or delete the entries.

    3. Expand Constraints and click the add (+) icon above the Constraint table.

      The Constraint page appears.

    4. Add the following parameters on the Constraints page:

      1. Click the Constraint Type drop-down and select constraint type from the following supported options:

        Note: Note: To apply the constraint, the connections in a site network access must be in the same group. For example, to ensure that the pop-diverse constraint type is applied on two connections in a site network access, both the connections must be in the same group and target group.

        • pe-diverse—The site network access (connection) must not be connected to the same PE router as the connections in the target group.

        • pop-diverse—The site network access must not use the same point-of-presence (POP) as the connections in the target group.

    5. Expand Target and click the add (+) icon above the Group ID table.

      The Group page appears.

    6. Click the Group ID drop-down to select the group to which you want to apply the constraint and click OK.

      The ID you enter is displayed in the Group ID table.

      You can add multiple group IDs as target groups to apply the access constraint.

    7. Click OK on the Constraint page.

      The constraint types and target group IDs are listed in the Constraint table.
