Abstract

An example method is provided and includes receiving a bridge protocol data unit (BPDU) on a particular link of a network. A port associated with the particular link is blocked in response to receiving the BPDU. The method also includes communicating a claim message to a spanning tree protocol (STP) root of the network; receiving, from a network element, a reply in which a grant bit is set; and changing the port associated with the particular link to a forwarding state.
