300-415 Question 137
Select 3A network engineer is tasked with configuring TLOCs for a Cisco SD-WAN deployment. The engineer needs to ensure that the TLOCs are correctly defined to support redundant transport types and provide a reliable connection between vEdge routers. Which of the following configurations are required to properly define a TLOC in this scenario?
- A
Each TLOC must be uniquely identified by a combination of color, encapsulation, and system IP.
- B
The TLOC configuration must include a transport type, such as MPLS or Internet.
- C
TLOCs can only be configured using the vManage GUI, and not through CLI.
- D
The encapsulation type for the TLOC must match the encapsulation type of the transport interface.
- E
TLOCs must be manually assigned to VPN 0 on vEdge routers.
Show answer and explanation
Correct answers: A, B, D
Explanation
TLOCs (Transport Locator Objects) are key components in Cisco SD-WAN architecture that define the transport paths used by vEdge routers to communicate. A TLOC is uniquely identified by the combination of system IP, color, and encapsulation, and it also requires a transport type to specify the underlying network (e.g., MPLS or Internet). The encapsulation type must match the transport interface to ensure proper operation. While TLOCs are generally associated with VPN 0, they do not need to be manually assigned to it, and they can be configured using both the CLI and vManage GUI.
- A. Correct.
Correct: TLOCs are uniquely identified by a combination of color, encapsulation, and system IP. This ensures that each TLOC is distinct in the Cisco SD-WAN fabric.
- B. Correct.
Correct: The transport type (e.g., MPLS, Internet) is a key parameter of the TLOC configuration as it defines the underlying transport for communication.
- C. Incorrect.
Incorrect: TLOCs can be configured using both the vManage GUI and CLI. The vManage GUI is not the only method for configuration.
- D. Correct.
Correct: The encapsulation type (e.g., IPsec, GRE) must match between the TLOC and the transport interface to ensure proper communication.
- E. Incorrect.
Incorrect: TLOCs are associated with transport interfaces that are part of VPN 0 by default. Manual assignment to VPN 0 is not required.
