Abstract

See full text

In one embodiment, a bridge in a computer network may execute a spanning tree protocol (STP) for network topology and a registration protocol for traffic control of virtual connections (e.g., EVCs) at the bridge. For any gateway ports of the bridge inter-connected with a provider network, the bridge may generate “fake” received registration protocol join messages for a particular virtual connection at the gateway port. The bridge may then either i) propagate the join messages, in response to the gateway port being in a forwarding state according to the STP, on other forwarding ports of the bridge, or ii) in response to the gateway port not being in a forwarding state, block propagation of the join messages to other ports of the bridge.
