Add EVPN Service Post Update Placements Parameters

You can configure placement parameters for the EVPN service when you are creating or modifying the service instance. Use Update placements button on the Customer Site Settings page to automatically assign possible placement options for the service instance.

You must create an EVPN service instance and add general, site, and site network access details before you update the placements parameters about the service. See Add an EVPN Service Instance and Add EVPN Site and Site Network Access Details.

To configure placement parameters:

  1. Click the Update Placements button on top of the Customer Site Settings page and click Yes when prompted to confirm.

    The service instance is saved to the Routing Director database. The saved instance is listed in the Service Instances table on the Service Instances page.

    Service orchestration automatically assigns possible placement options such as PE devices and interfaces, CE devices, and VLANs for the service instance. After placement options are assigned, a confirmation message appears indicating that the placement was successfully updated.

  2. Click Back on the Customer Site Settings page to configure placement parameters in the fields on the General page.

  3. To add placement parameters on the General page:

    1. Expand Route Target and configure the placement parameters by referring to the following table:

      Table 1: Route Target (EVPN)

      Field

      Description

      Number

      Enter the number of route targets.

      The block size entered when configuring a VPN resource pool is the upper limit for the route target number. The entered block size is displayed to the right of the text box.

      Pool

      Select a pool value.

      The ASN values specified when configuring a VPN resource pool are available as options in the drop-down list.

    2. Expand Placement IRB and configure the placement parameters.

      Select the PE node and click the edit icon. The Placement IRB page appears.

      Configure the placement parameters by referring to the following table:

      Table 2: Placement IRB (EVPN)

      Field

      Description

      If you selected vlan-based as the EVPN service type:

      PE Node

      Displays the PE device assigned to the IRB instance.

      IRB

      Enter the IRB interface ID for the PE device from the available range of interface IDs.

      The available range of IRB interface IDs is specified when you configure the topology resource instance and is displayed next to the IRB text box.

      If you selected vlan-aware as the EVPN service type:

      PE Node

      Displays the PE device assigned to the IRB instance.

      VLAN

      Displays the VLAN ID assigned to the PE device.

      IRB

      Enter the IRB interface ID for the PE device from the available range of interface IDs.

      The available range of IRB interface IDs is specified when you configure the topology resource instance and is displayed next to the IRB text box.
      Note: Configuring IRB interfaces for an E-LAN EVPN CSM service is qualified only for the following scenarios:

      • EVPN with Ethernet interface port mode.

      • EVPN with Ethernet interface VLAN mode.

      • EVPN with Aggregate Ethernet interface port mode.

      • EVPN with Aggregate Ethernet interface VLAN mode.

      • Multihomed EVPN with Aggregate Ethernet interface port mode.

      • Multihomed EVPN with Aggregate Ethernet interface VLAN mode.

    3. Expand Route Distinguishers and configure the service instance to see the assigned RDs.

      1. Select a PE Node and click the edit icon. The Route Distinguisher - Type selected-type page appears.

        Configure the parameters by referring to the following table:

      Description

      If you selected type0 as the Route Distinguisher Type:

      PE Node

      The name of the PE node device.

      Pool

      The unique RD identifier configured as the ASN in the VPN resource pool.

      When the service is configured, the combination of the pool ID a Routing Director assigned number is visible in the device CLI in the format pool:number. For example, 60000:9.

      Number

      A unique number assigned to the RD by Routing Director. In the previous example, the number is 9.

      If you selected type1 as the Route Distinguisher Type:

      PE Node

      Name of the PE node device.

      IP Address

      Loopback address of the device.

      If you want to change the loopback address for the device, you can edit the entry from the available preconfigured loopback addresses. To edit, select the RD, click the pencil icon, and select another loopback address from the drop-down list.

      Name

      Unique RD identifier populated from the configured names in the topo resource instance.

      Assigned Number

      A unique number assigned to the RD by Routing Director from the block size configured in the topo resource instance.

      To change the assigned number, select the RD, click the pencil icon, and edit the number from the preconfigured range visible next to the textbox.

      When the service is configured, the combination of the loopback address and the assigned number is visible in the device CLI in the format loopback_IP:number. For example, 192.168.1.1:30.

    4. Expand Placement ESI (Ethernet Segment Identifier) and configure the placement parameters.
