The ip route recursive-lookup arp vlink-direct-route protocol static command configures a device to recurse static routes to ARP Vlink routes.
The undo ip route recursive-lookup arp vlink-direct-route protocol static command disables a device from recursing static routes to ARP Vlink routes.
By default, static routes cannot recurse to ARP Vlink routes.
Usage Scenario
In a scenario where a Layer 2 VPN accesses a Layer 3 VPN, to configure a device to recurse static routes to ARP Vlink routes, run the ip route-static command with recursive-lookup host-route specified and ip route recursive-lookup arp vlink-direct-route protocol static.
If a Layer 2 link fails, for example, the physical interface of a Layer 2 device fails, traffic can be switched to the backup path immediately, preventing traffic loss caused by a black-hole route.Precautions
After the ip route recursive-lookup arp vlink-direct-route protocol static command is run, all static routes can recurse to ARP Vlink routes. After the undo ip route recursive-lookup arp vlink-direct-route protocol static command is run, static routes cannot recurse to ARP Vlink routes..
