What is a Transport Locator (TLOC)?
A Transport Locator (TLOC) is the connection point between a WAN transport and Cisco WAN Edge device. It is represented by a tuple of values: the system IP address, the transport color and the encapsulation type.
The system IP address identifies the Edge device across the entire SD-WAN, though it doesn't need to be reachable or routable across it. The address is used in a similar way as the router ID is used in protocols such as BGP (Border Gateway Protocol).
The transport color is one of the colors that you have defined for the different types of WAN transports in your network, such as MPLS, Internet and LTE. If for some reason you duplicate transports, such as for different providers of them, you should use a different color for each.
The encapsulation type of the TLOC can be either IPsec (Internet Protocol Security) or GRE (Generic Routing Encapsulation). Both sides of the connection must use the same encapsulation type.
