VPRN data plane: A data packet arrives at the ingress PE and is encapsulated with both the outer/transport label, learned through LDP, as well as the service label, learned through T-LDP or MP-BGPAs the data packet traverses the P routers, the outer label is swapped while the inner label remains...
