Abstract
A method for resolving primary section mismatch at a local node coupled to a remote node with two working sections is disclosed. A first working section is initially identified as the primary section and a second working section is initially identified as the secondary section. The primary section supports network traffic and the secondary section operates as a backup for the primary section. The method includes receiving a status indication change of the working section identified as the primary section at the local node and switching the primary section to the second working section at the local node. A timer is started upon switching the primary section to the second working section at the local node and the primary section is switched back to the first working section at the local node after the timer expires if the other node has not switched its primary section.
