Abstract
In one embodiment, a method includes sending upstream to a nearest neighbor node, by a Client Label Switched Router (LSR), a downstream label map message of a Server-Forwarding Equivalence Class type (S-FEC-DOWN). In response to the S-FEC-DOWN, a downstream forwarding state from the nearest neighbor node to the Client LSR is established. An upstream label map message of a Client-Forwarding Equivalence Class type (C-FEC UP) is received from the nearest neighbor node. An upstream forwarding state corresponding to the C-FEC UP is then established by the Client LSR.
