All instances of VRRP (Virtual Router Redundancy Protocol) have host-mobility off by default. Configuring host-mobility to “on” state starts ARP route learning. By default, all ports perform the route learning. Configuring host-mobility excluded-ports will disable the route learning on the port list provided. All ports of the VRRP VLAN (Virtual LAN) that are connected to another router should be excluded. If ports are not excluded, routes are created for devices as if they are directly connected and this may cause traffic to take a longer route.
| host-mobility | Exportable Host Route learning via ARP/ND on the specified VLAN and VRID. |
| on | Advertise host routes for hosts learned via ARP/ND. |
| off | Do not advertise host routes for hosts learned via ARP/ND. |
| exclude-ports | Exclude ports from host-mobility route learning (Default: no ports are excluded). |
| add | Add ports to host-mobility exclude list; host-mobility routes will not be learned on the ports. |
| delete | Delete ports from host-mobility exclude list. |
| port_list | Port list separated by a comma or –“ . |
| vlan_name |
Specifies the name of a VRRP VLAN. |
| vlan_list | VLAN list (1–4,094). |
| vridval |
Specifies the VRID for the VRRP instance. To display the configured VRRP router instances, enter the show vrrp command. |
| vrid_list | List of virtual router IDs (1–255). |
| all | Selects all VRRP virtual routers. |
Off.
Configuring host-mobility excluded-ports will disable the route learning on the port list provided. All ports that are connected to another router should be excluded.

This command was first available in ExtremeXOS 21.1.
VLAN and VR list options added in ExtremeXOS 22.3.
The all option was added in ExtremeXOS 22.4.
This command is available on platforms that support the appropriate license. For complete information about software licensing, including how to obtain and upgrade your license and which licenses support the VRRP feature, see the ExtremeXOS 22.4 Feature License Requirements document.
