Explanation

A TLOC route in Cisco SD-WAN is uniquely identified by the combination of the WAN Edge router's system IP address, the link's color, and the encapsulation type.

Common mistakes.

  • B. Origin, originator, and preference are attributes associated with OMP routes used for path selection, not for uniquely identifying a TLOC.
  • C. Site ID and VPN are important for network segmentation and topology but are not direct attributes that uniquely identify a specific TLOC itself; tag is an OMP attribute.
  • D. Firewall, IPS, and application optimization are types of network services or features, not attributes used to uniquely identify a TLOC route.
