Precautions
When configuring a static route, note the following:
1) If you do not specify the preference when configuring a static route, the default preference will be
used. Reconfiguration of the default preference applies only to newly created static routes.
Currently, the Web interface does not support configuration of the default preference.
2) When configuring a static route, the static route does not take effect 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.
3) When specifying the output interface, note that:
If NULL 0 or a loopback interface is specified as the output interface, there is no need to configure
the next hop address.
If a point-to-point interface is specified as the output interface, you don’t 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, and 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. Therefore, you are
recommended to specify the next hop IP address 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 may have multiple next hops, you must specify the
next hop at the same time.
