Abstract
Methods, devices, and computer-readable medium for preventing broadcast looping during a site merge are described herein. An example method can include detecting a site merge between a plurality of layer 2 (L2) networks using a spanning tree protocol (STP), blocking a data traffic port connecting the L2 networks in response to detecting the site merge, and performing an STP-Ethernet virtual private network (EVPN) handshake. The STP-EVPN handshake can include changing a root bridge in one of the L2 networks. Thereafter, the method can include unblocking the data traffic port connecting the L2 networks. In other words, the data traffic port connecting the L2 networks can be unblocked after changing the root bridge in the one of the L2 networks.
