IP and MAC Anycast

This feature enables you to configure the anycast gateway MAC to be used by VLANs that enable IP anycast. You can specify the same IP address and MAC address on all edge technology devices, which allows seamless IP mobility in the network for edge devices.

Note

This feature was released as a demonstration feature in ExtremeXOS 30.6. It is now fully supported in ExtremeXOS 30.7.

Supported Platforms

Limitations

Switching through a VXLAN tunnel to a remote L3 anycast gateway is not supported.
