(Optional) Configuring a Device to Iterate Static Routes to ARP Vlink Routes

To prevent traffic loss caused by a black-hole route in a scenario where a Layer 2 VPN accesses a Layer 3 VPN, configure devices to iterate static routes to ARP Vlink routes.

Context

Configuring a device to iterate static routes to ARP Vlink routes prevents traffic loss caused by a black-hole route in a scenario where a Layer 2 VPN accesses a Layer 3 VPN.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run ip route recursive-lookup arp vlink-direct-route protocol static

    Static routes are allowed to recurse to ARP Vlink direct routes.

    The ip route recursive-lookup arp vlink-direct-route protocol static command is mainly used in scenarios where a Layer 2 network accesses a Layer 3 network. This command is used with the recursive-lookup host-route parameter in the ip route-static command to configure static routes to recurse only to ARP Vlink direct routes.

  3. Run commit

    The configuration is committed.
