Networking Requirements

Figure 1-9 shows the SD-WAN networking of Enterprise A. During the setup of an SD-WAN network, the tenant administrator needs to configure connectivity between the CPEs and the WAN-side network.

Solution Design

Based on customer requirements and the networking plan, the tenant administrator has created the hub site and branch sites. To configure routes for the underlay network, perform the following tasks:

  1. BGP is supported in the MPLS network on the WAN side, allowing BGP routes to be configured on the underlay network for connecting the CPEs and the MPLS network. To improve the security of the BGP routing protocol, MD5 authentication is enabled.
  2. Since BGP is not supported in the Internet, static routes need to be configured to connect the CPEs to the Internet.
  3. The information about BGP peers needs to be configured on the CPE of each site to enable interconnection between the site and the MPLS network. No routing policy needs to be configured because currently there is no need to restrict the network segments in which BGP routes are advertised and received. This means all BGP routes are advertised and received in every network segment.
  4. When configuring static routes for Internet access, you need to configure a default route. The Internet link at Site2 obtains a dynamic IP address through PPPoE. Therefore, an outbound interface is specified as the next hop of the default route. To quickly detect network faults, you are advised to set an IP address that is reachable through a public network route as a probe address. The system then creates an NQA instance using this address as the destination address for detecting link connectivity. In this example, the probe address is 10.110.42.160.

Procedure

  1. Log in to the Agile Controller-Campus as a tenant administrator.
  2. Finish creating sites.
  3. Configure routes for the underlay network of the hub site.

    1. Choose Configuration > Site > Underlay Configuration.
    2. Select Hub1 from the left list and click WAN Route.
    3. On the WAN Route page that is displayed, click Click Here to Add Routing Protocol and select BGP.
    4. On the BGP page, click Advanced Settings and enable Default route redistribution.

    5. On the BGP page, click Create and set BGP route parameters.

    6. On the WAN Route page that is displayed, click and select Static. Click Create and set static route parameters. On the main page, click Apply Changes.

  4. Configure routes for the underlay networks of the branch sites.

    1. Perform the same operations as those for the hub site to complete BGP route parameter configuration for Site2 and click Apply Changes.

    2. Configure static routes for Site2, and click Apply Changes.

    3. Configure BGP routes for Site3, and click Apply Changes.

    4. Configure static routes for Site3, and click Apply Changes.
