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

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

  1. Click the + (Add) icon on the top-right corner of the Sites section.

    The Add Site page appears.

  2. Enter site ID, location, and device values by referring to Table 1.

    1. Expand Maximum Routes and click the + (Add) icon on the top-right corner of the Address Family section.
      The Address Family page appears.
    2. Enter the maximum routes value.
      This value indicates the number of routes that the VRF can accept for the IPv4 address family. Paragon Automation currently supports only the IPv4 address family.
    3. Click OK.
      The details you entered are listed in the Address Family table.
    4. (Optional) To edit or delete an entry, use the edit or delete options present above the Address Family table.
  4. Do any of the following:

    • Click Cancel to exit the Add Site page without saving the changes you made.

To set site network access parameters:

  1. Select and expand the site name in the Sites table.
  2. Click the + (Add) icon above the Site Network Access table.
    The Add Connection page appears.
  3. Enter the site network access ID and device reference values by referring to Table 2.
  4. Expand Access Diversity and add the access diversity parameters. See Add Access Diversity Parameters.
  5. Expand Bearer and add the bearer parameters by referring to Table 2.
  6. Expand IP Connection > IPv4 and add the connection parameters by referring to Table 2.
  7. Expand Routing Protocols and add the routing protocols. See Add Routing Protocols.
  8. Expand Service and add the service parameters by referring to Table 2.
  9. Expand VPN Attachment and enter the value by referring to Table 2.
  10. Do any of the following:

    • Click Cancel to exit the Add Connection page without saving the changes you made.

    • Click OK to save the connection details you added.

      You are returned to the Add L3 VPN Service page and view the connection you added listed in the Site Network Access table.

Add Access Diversity Parameters

A Network Admin 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. 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.

    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 Constraints 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 available options as listed in Table 2.
    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 the constraint must be applied.
      You can add multiple group IDs for target groups. The group IDs you add are listed in the Group ID table.
    4. (Optional) Use the edit or delete options above the Constraints table to edit or delete the entries.
    5. Click OK on the Constraint page.
      The constraint types and target group IDs are listed in the Constraint table.

Add Routing Protocols

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 + (Add) present above the Routing Protocols table and set the routing protocol from the supported options:
    Note:

    • The hub-and-spoke VPN topology is a beta feature in this release.

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

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