Add L3VPN Service Site Details

An L3VPN service is provisioned on a collection of sites to exchange network traffic over a shared IP infrastructure. Use the Site Settings section of the Add L3 VPN Service page to enter details of sites that you want to connect to the VPN.

You configure the following in the Site Settings section:

Add L3VPN Site

Prerequisite

Before adding the L3VPN service site details, you must create a new L3VPN service instance and enter general details about the service. Follow steps 1 to 4 of the Add an L3VPN Service Instance procedure to create a new instance and add L3VPN service general details.

An L3VPN site refers to the geographical area where the VPN service spans. To add an L3VPN service site in the Site Settings section:

    The Constraint page appears.
  4. Add the following parameters on the Constraints page:
    1. Click the Constraint Type drop-down and select the constraint type from the following supported options:.

      • pe-diverse—The site network access must not be connected to the same PE router as the target connections from the site.

      • same-pe—The site network access must be connected to the same PE router as the target connections from the site.

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

    2. Expand Target and click the add (+) icon above the Group ID table.
      The Group page appears.
    3. 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.

Add Routing Protocol for L3VPN Site Network Access

Prerequisite:

Complete steps 1 to 6 of the Add L3VPN Site Network Access Parameters procedure.

The Routing Protocols section defines the routing protocol to be used between the PE and CE routers.

In a customer-managed site, the routing protocol that you define here is used between the PE router and CE router that the customer manages. In a service provider-managed site, the routing protocol that you define here is used between the provider-managed CE router and the customer-managed LAN or router. Paragon Automation supports the static route, direct, OSPF, and BGP protocols for L3VPN service provisioning.

To set routing protocols:

  1. Expand Routing Protocols on the Add Connection page.
  2. Click the Add button present above the Routing Protocols table and set the routing protocol from the supported options:
    Note:

    The hub-and-spoke topology supports only the static route protocol.

    • Static route—To set the static route protocol:

      1. Expand Routing Protocols and click Add > Static Route on the Add Connection page.

        The Add Static Route page appears.

      2. Expand Cascaded LAN Prefixes and click the add (+) icon next to Ipv4 LAN Prefixes.

        The IPv4 LAN Prefixes page appears.

      3. Enter the values as described in the following table:

        Table 6: Static Route Parameters (L3VPN)

        Field

        Description

        LAN

        Enter the IPv4 address with prefix from the customer LAN to be routed through the L3VPN connection. For example, 192.168.0.1/20.

        Next Hop

        Enter the IPv4 address of the next hop router to be used for forwarding packets in the static route. For example, 10.1.0.1.

        Note:

        In the L3VPN hub-and-spoke topology, by default, the spokes cannot communicate with each other and they can only reach the hub CE device. To ensure that spokes communicate with each other through the hub CE device, add a 0.0.0.0/0 LAN interface with the customer device interface IP address as the next hop.

      4. Click OK.

        The static route details are listed in the IPv4 LAN Prefixes table.

      5. (Optional) To edit or delete an entry, select the entry and click the edit or delete icons present above the IPv4 LAN Prefixes table.

        The Add BGP page appears.

      2. In the Autonomous System field, enter the autonomous system number of the network in which you want to configure the L3VPN service.

      3. Click OK.

        The BGP details are listed in the Routing Protocols table.

    • Direct—Use the direct routing protocol when a customer LAN at the site is directly connected to the service provider network.

      To use the direct routing, click Add > Direct. The entry is listed in the Routing Protocols table.

  3. (Optional) To edit or delete an entry, select the entry and click the edit or delete icons present above the Routing Protocols table.
