Configuration guidelines
When you configure a static route, follow these guidelines:
• If you do not specify the preference, the default preference is used. Reconfiguration of the default
preference applies only to newly created static routes. The Web interface does not support
configuration of the default preference.
•
If you specify the next hop address first and then configure it as the IP address of a local interface,
such as an Ethernet interface and VLAN interface, the static route does not take effect.
•
When you specify the output interface, note the following:
If Null 0 or a loopback interface is specified as the output interface, there is no need to
configure the next hop.
If a point-to-point interface is specified as the output interface, you do not need to specify the
next hop, and there is no need to change the configuration after the peer address has changed.
For example, a PPP interface obtains the peer's IP address through PPP negotiation. Therefore,
you only need to specify it as the output interface.
If the output interface is an NBMA or P2MP interface, which supports point-to-multipoint
networks, the IP address-to-link layer address mapping must be established. HP recommends
specifying the next hop when you configure it as the output interface.
If you want to specify a broadcast interface (such as an Ethernet interface, virtual template, or
VLAN interface) as the output interface, which can have multiple next hops, you must specify the
next hop at the same time.
