Transport Locator (TLOC)

A Cisco SD-WAN identifier of a WAN Edge transport attachment point: system IP, color and encapsulation.

Definition

Each WAN interface with a public or private IP is a TLOC. OMP routes point to TLOCs as next hops, and IPsec/GRE data tunnels form between TLOCs, monitored by BFD. Colors (such as mpls, biz-internet, lte) and restrict settings govern which TLOCs form tunnels.

Example

color biz-internet restrict under tunnel-interface

Exam tip

Color 'restrict' limits tunnels to TLOCs of the same color.
