Abstract

In one embodiment, a bridge may receive a first convergence proposal on a root port from an upstream adjacent bridge of a computer network, and in response, may transmit a second convergence proposal downstream on each non-edge designated port of the bridge without syncing the non-edge designated ports. The bridge may then return a convergence agreement to the adjacent bridge in response to the non-edge designated ports having received a returned convergence agreement (or in response to having only edge designated ports). Also, according to embodiments, the adjacent bridge blocks a link to the root port until the convergence proposal(s) and agreement(s) travel end-to-end.
