1. A method, comprising:
originating, by a network device, a route;
pruning, by the network device, the route as a first colored route having a first color;
wherein a color was not initially designated for the route;
designating, by the network device, the route as the first colored route having the first color;
advertising, by the network device, the first colored route to a first intermediate network device to cause the first intermediate network device to propagate the first colored route to an ingress network device over a first colored border gateway protocol session,
wherein the first color belongs to the first colored border gateway protocol session;
designating, by the network device, the route as a second colored route having a second color; and
advertising, by the network device, the second colored route to a second intermediate network device to cause the second intermediate network device to propagate the second colored route to the ingress network device over a second colored border gateway protocol session.
