What Attributes Can You Associate with a TLOC?

The main attributes of a TLOC (and what uniquely defines them) are IP address, color and encapsulation. The IP address is the address of the source device upon which the interface is located. The color is the identifier of the TLOC type. The encapsulation represents the tunnel encapsulation, which can be either IPsec or GRE.

Other attributes that you can associate with a TLOC include the carrier, which identifies the carrier type and primarily signifies whether the transport is public or private. The domain ID identifies the overlay network domain. The originator is the IP address of the originating node. The preference is the OMP path-selection preference, with higher values representing more preferred paths. The site ID identifies a site, each of which can have multiple TLOCs. Finally, the tag is an arbitrary TLOC identifier.

You configure all TLOC attributes on the source device, apart from the originator attribute, which you configure on the originating node.
