  • Seamless migration from multiple spanning tree protocol to ethernet ring protection switching protocol
    Patent number: 9923731
    Abstract: Methods and systems are provided for migrating loop-breaking protocols in an Ethernet network. The method includes selecting a virtual local area network (VLAN) implementing a multiple spanning tree protocol (MSTP) from a plurality of VLANs operating on the Ethernet network, the MSTP having a spanning tree with a root network element coupled to a first branch of network elements; disabling a virtual network link in the VLAN; migrating a first leaf network element of the first branch in the VLAN by disabling the MSTP and enabling an Ethernet ring protection switching (ERPS) protocol on the first leaf network element; migrating the root network element in the VLAN after the first leaf network element by disabling the MSTP and enabling the ERPS protocol on the root network element; and enabling the virtual network link after migrating the first leaf network element and the root network element.
