Routing Protocols for BGP and OSPF

B.

In a Cisco SD-WAN solution, the component responsible for routing protocols such as BGP and OSPF is the WAN Edge Router.

The WAN Edge Router is one of the main components in the Cisco SD-WAN architecture, responsible for providing connectivity to the branch office and integrating different types of WAN links such as MPLS, Internet, and 4G/LTE. It also provides end-to-end segmentation and encryption of traffic, along with application optimization and control features.

Routing protocols such as BGP and OSPF are used to determine the best path for traffic to reach its destination across the WAN. These routing protocols help to dynamically learn and exchange information about the network topology, and choose the optimal path for traffic based on various parameters such as link speed, latency, and cost.

The WAN Edge Router is responsible for implementing and managing these routing protocols in the Cisco SD-WAN solution. It communicates with other WAN Edge Routers and vSmart Controllers to exchange routing information and ensure that the traffic is forwarded through the optimal path.

The other components in the Cisco SD-WAN solution such as vSmart Controller, vManage, and vBond Orchestrator, provide centralized management and orchestration of the WAN Edge Routers, but they are not responsible for implementing the routing protocols.

In summary, the WAN Edge Router is responsible for routing protocols such as BGP and OSPF in a Cisco SD-WAN solution. It implements and manages these protocols to ensure optimal traffic routing across the WAN.
