Abstract: This disclosure describes methods of operating a leaf node device, such as a switch device, connected to a switch fabric of a network. The leaf node device receives, from another leaf node device via the switch fabric, an indication of a secure route to a host device. In response to receiving the indication of the secure route, the leaf node device creates or updates a routing entry for the host device in a routing information base of the leaf node device and creates or updates an entry for the host device in a Dynamic Host Configuration Protocol (DHCP) snoop database of the leaf node device. The leaf node may thereby communicate with the host device that is attached to the leaf node device as a result of moving from the other leaf node device.

Abstract: Systems, devices, and methods for detecting an Ethernet segment failure in an Ethernet virtual private network (EVPN) are described herein. An example method can include monitoring for failure of an Ethernet segment, establishing a bidirectional forwarding detection (BFD) session with a remote peer, and transmitting a BFD control packet to the remote peer over a network. The BFD control packet can include a notification of the failure of the Ethernet segment.
