300-415 Question 22
Single answerYou are configuring a Cisco SD-WAN environment and need to ensure that traffic between two vEdge routers is routed through a specific transport link. The TLOC configuration on the vEdge devices needs to be properly defined. Which attribute of the TLOC is critical for identifying the specific transport link?
- A
System IP address
- B
Color
- C
Encapsulation type
- D
Service type
Show answer and explanation
Correct answer: B
Explanation
A TLOC (Transport Location) is a fundamental concept in Cisco SD-WAN that serves as the connection point to a specific transport network. Each TLOC is uniquely identified by three attributes: System IP, Color, and Encapsulation Type. Among these, the Color attribute is used to define the type of transport link, such as public-internet, mpls, or private links. This ensures that traffic is routed through the desired transport link based on policy or intent.
- A. Incorrect.
The System IP address is used to uniquely identify a device in the SD-WAN fabric, but it does not specify the transport link of the TLOC.
- B. Correct.
The Color attribute is critical in identifying the transport link in a TLOC, as it represents the type of transport (e.g., public-internet, mpls, etc.).
- C. Incorrect.
Encapsulation type (e.g., IPsec or GRE) is a part of the TLOC configuration, but it does not specifically identify the transport link.
- D. Incorrect.
Service type is not related to the TLOC's transport link identification; it is used for defining specific services in SD-WAN.
