Abstract
A source node encapsulates, in a data plane protocol packet, a forward tunnel control message according to a control plane protocol and having an Extended Association Object, and forwards the data plane protocol packet from a source node to a destination node, through a data plane channel. The destination node extracts the Extended Association Object from the data plane protocol packet. Based, at least in part, on the extracted Extended Association Object, the destination node provisions a reverse tunnel from the destination node to the source node, and binds the forward tunnel to the reverse tunnel.
