Claim 15:
16. A non-transitory computer-readable medium comprising instructions that, when executed, are configured to cause processing circuitry of a border node capable of being positioned at a border of a first administrative domain and a second administrative domain to:
receive a transport route specifying: first data indicating one or more underlay tunnels configured to support a service route, and second data indicating a route target to cause routers receiving the service route to import the service route to use the one or more underlay tunnels, the service route being a logical route for transporting network traffic associated with a first network service to a customer edge device that receives the network traffic associated with the first network service, wherein the first network service comprises one of a plurality of network services;
store, based on the first data and the second data, data indicative of a first transport class of a plurality of transport classes, wherein the first transport class is a service-specific group comprising the route target and specifying the one or more underlay tunnels that belong to the service-specific group, and wherein the route target of the first transport class is different from route targets of each other transport class of the plurality of transport classes;
store an association between the service route and the first transport class to enable stitching together the one or more underlay tunnels of the first administrative domain with one or more underlay tunnels of the second administrative domain;
receive the network traffic associated with the first network service via one or more underlay tunnels of the second administrative domain;
identify the network traffic associated with the first network service as being associated with the service route for the first network service of the plurality of network services; and
forward, based on the association between the service route and the first transport class of the plurality of transport classes, the network traffic associated with the first network service of the plurality of network services along the one or more underlay tunnels specified by the first transport class.
