1. Destination address and mask
In the ip route-static command, an IPv4 address is in dotted decimal format and a mask can be either in
dotted decimal format or in the form of mask length—the number of consecutive 1s in the mask.
2. Output interface and next hop address
When configuring a static route, specify either the output interface, next hop address, or both depending
on the specific occasion. The next hop address cannot be a local interface IP address; otherwise, the
route configuration will not take effect.
In fact, each route lookup operation has to find the next hop to resolve the destination link layer address.
When specifying the output interface, observe the following rules:
• If the output interface is a Null 0 interface, no next hop address is required.
• H3C does not recommend you to specify a broadcast interface (such as a VLAN interface) as the
output interface, because a broadcast interface may have multiple next hops. If you have to do so,
you must specify the corresponding next hop for the output interface.
3. Other attributes
You can configure different priorities for different static routes so that route management policies can be
more flexible. For example, specifying the same priority for different routes to the same destination
enables load sharing, but specifying different priorities for these routes enables route backup.
Configuring a static route
Configuration prerequisites
Before configuring a static route, complete the following tasks:
• Configure the physical parameters for related interfaces
• Configure the link-layer attributes for related interfaces
• Configure the IP addresses for related interfaces
Configuration procedure
Follow these steps to configure a static route:
