Abstract
Systems and methods are provided herein for supporting Spanning Tree Protocol (STP) in networks that use Ethernet Virtual Private Network (EVPN) All-Active (A-A) multihoming. This may be accomplished by a network administrator defining a super root group comprising a plurality of network devices, wherein each network device provides A-A multihoming to a multihomed device. All network devices in the super root group use a common bridge ID when generating BPDU messages for STP. All network devices in the super root group will send BPDU messages comprising the common bridge ID to the multihomed device. Because the BPDU messages comprise a common bridge ID, the multihomed device treats the network devices in the super root group as a single local bridge, thus STP is enabled without causing STP flapping.
