SD-WAN Design

Question 1

What is vSmart in Cisco SD-WAN Architecture?

Answer 1

Centralized Control Plane Controller

Question 2

What is vBond Orchestrator in Cisco SD-WAN Architecture?

Answer 2

Assists in the automatic on-boarding of SD-WAN routers and authenticates Cisco vEdge devices as they join the network

Question 3

What is the vSmart controller in Cisco SD-WAN Architecture?

Answer 3

Centralized brain of Cisco SD-WAN that establishes a secure connection to each vEdge router and distributes routes and policy information via the Overlay Management Protocol (OMP) similar to iBGP and makes vSmart acting as a route reflector.

Question 4

What is the vManage Network Management System (NMS) in Cisco SD-WAN Architecture?

Answer 4

Centralized network management system to monitor, configure and maintain all SD-Wan devices and links in the underlay and overlay network.

Question 5

What is the vEdge in Cisco SD-WAN Architecture?

Answer 5

Either hardware appliance or software-based router that sites at the edge of the WAN to provide secure data plane connectivity for ingress/egress traffic for the SD-WAN fabric.

Question 6

What is the vEdge responsible for in a Cisco SD-WAN Architecture?

Answer 6

Traffic forwarding, security, encryption, Quality of Service (QoS) and routing protocols and more

Question 7

What is Overlay Management Protocol (OMP) in Cisco SD-WAN Architecture?

Answer 7

establishes and maintains routing, policy and management information between vSmart controllers and vEdge routers similar to iBGP

Question 8

What does vEdge TLOC stand for?

Answer 8

Transport Location

Question 9

What are TLOC used for in SD-WAN?

Answer 9

Uniquely identify the circuit interface to the control plane and data plan information.

Question 10

What 3 things does the TLOC consist of?

Answer 10

System IP (like a Router ID)

Circuit Interface Color (attribute to identify individual WAN transport tunnels)

Encapsulation Protocol
