Usage guidelines
When the following conditions exist, a recursive static route becomes inactive:
•
The static route uses a host route to reach its direct next hop.
•
The host route is obtained either by specifying the
recursive-lookup host-route
keyword in the
ip route-static
command or by routing policy-based recursive lookup.
•
The host route is unavailable because the direct next hop cannot send gratuitous ARP
messages and consequently no ARP entry exists for that host route on the device.
To resolve this issue, you can use this command to enable the device to periodically send ARP
requests to the direct next hop. When the device receives an ARP response from the direct next
hop, it stops sending ARP requests and activates the recursive static route.
This command applies only to a recursive static route that meets the following requirements:
•
The static route has no output interface specified.
•
The static route fails the next-hop recursion.
Examples
# Enable sending of ARP requests to the next hops of static routes and set the sending interval to
10 seconds.
<Sysname> system-view
[Sysname] ip route-static arp-request interval 10

ip route-static default-preference
Use
ip route-static default-preference
to configure a default preference for static
routes.
Use
undo ip route-static default-preference
to restore the default.
Syntax
ip route-static default-preference default-preference
undo ip route-static default-preference
Default
The default preference of static routes is 60.
Views
System view
Predefined user roles
network-admin
Parameters
default-preference : Specifies a default preference for static routes, in the range of 1 to 255.
Usage guidelines
If no preference is specified for a static route, the default preference applies.
When the default preference is reconfigured, it applies only to newly added static routes.
