ELRP with Virtual Extensible LAN (VXLAN)

Starting with ExtremeXOS 22.4, ELRP is supported on Virtual Extensible LAN (VXLAN).

VXLAN is an encapsulation mechanism. A VXLAN header is added to an L2 (ELRP PDU) frame and encapsulated in a UDP/IP packet. Transit nodes see only an ordinary IP packet. For more information about VXLAN, see VXLAN.

ELRP detects loops across VXLAN tunnels. If a loop is detected across the tunnel and the disable-port option is configured (see Configuring Periodic Requests), ELRP takes down the VXLAN remote endpoint.

If the VXLAN remote endpoint has been disabled using the permanent option, you can use the following command to re-enable the remote endpoint:

enable virtual-network remote-endpoint vxlan [ ipaddress ipaddress {vr vr_name} | all ]

To manually disable a remote endpoint, use the following command:

disable virtual-network remote-endpoint vxlan [ ipaddress ipaddress {vr vr_name} | all ]

To see if a remote endpoint is enabled or disabled, use the following command:

show virtual-network {vn_name} remote-endpoint vxlan {vni vni} {ipaddress ipaddress {vr vr_name}}
