Introduction to Building an SD-WAN Network

Introduction to Building an SD-WAN Network

An SD-WAN network is designed based on the customer's network environment, service and networking scenarios, site scale, and service requirements. Network configurations are delivered through the Agile Controller-Campus, and site deployment is completed at the site. Figure 1-1 shows the procedure of configuring an SD-WAN network on the Agile Controller-Campus and deploying a site. For the detailed procedure, see section Example for Building an SD-WAN Network for an Enterprise Tenant.

Figure 1-1 SD-WAN network configuration procedure

The procedure of configuring a new SD-WAN network consists of multiple steps, each of which consists of a set of configurations. Typical configuration examples for each step are provided in this chapter. Based on these examples, an SD-WAN network can be configured to fulfill different networking and service requirements.

Table 1-1 illustrates eight typical networking scenarios and provides configuration examples for each step. The following describes each of the scenarios:

  • Scenario 1: The WAN-side enterprise networks are a Layer 3 MPLS network and the Internet. BGP is used for WAN-side routing in the underlay network. Only one hub site is deployed, and branch sites access the Internet in centralized mode through LAN-side links of the hub site.
  • Scenario 2: The WAN-side enterprise networks are a Layer 3 MPLS network and the Internet. BGP is used for WAN-side routing in the underlay network. Only one hub site is deployed, and branch sites centrally access the Internet through WAN-side links of the hub site.
  • Scenario 3: The WAN-side enterprise networks are a Layer 3 MPLS network and the Internet. BGP is used for WAN-side routing in the underlay network. An active hub site and a standby hub site are deployed, and branch sites centrally access the Internet through LAN-side links of the hub sites.
  • Scenario 4: The WAN-side enterprise network is a Layer 3 MPLS network. BGP is used for WAN-side routing in the underlay network. An active hub site and a standby hub site are deployed, and branch sites centrally access the Internet through LAN-side links of the hub sites.
  • Scenario 5: The WAN-side enterprise networks are a Layer 2 MPLS network and the Internet. OSPF is used for WAN-side routing in the MPLS underlay network, and BGP is used for WAN-side routing in the Internet underlay network. An active hub site and a standby hub site are deployed, and branch sites centrally access the Internet through LAN-side links of the hub sites.
  • Scenario 6: The WAN-side enterprise network is a Layer 2 MPLS network. OSPF is used for WAN-side routing in the underlay network. An active hub site and a standby hub site are deployed, and branch sites centrally access the Internet through LAN-side links of the hub sites.
  • Scenario 7: The WAN-side enterprise networks are a Layer 3 MPLS network and the Internet. BGP is used for WAN-side routing in the MPLS underlay network, and static routes are used for WAN-site routing in the Internet underlay network. An active hub site and a standby hub site are deployed, and branch sites centrally access the Internet through LAN-side links of the hub sites.
  • Scenario 8: The WAN-side enterprise network is a Layer 3 MPLS network. An active hub site and a standby hub site are deployed. BGP is used for WAN-side routing in the underlay network. Two departments need to be configured for the enterprise, and network services of the two departments need to be deployed independently without affecting each other. Branch sites centrally access the Internet through LAN-side links of the hub sites.
