Default route

A default route is used to forward packets that match no entry in the routing table.
Without a default route, a packet that does not match any routing entries is discarded and an Internet
Control Message Protocol (ICMP) destination-unreachable packet is sent to the source.
You can configure default routes in the Web interface in the following ways:
Configure an IPv4 static default route and specify both its destination IP address and mask as
0.0.0.0.
Configure an IPv6 static default route and specify both its destination IP address and prefix as ::/0.

Configuration guidelines

When you configure a static route, follow these guidelines:
If you do not specify the preference, 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.
If you specify the next hop address first and then configure it as the IP address of a local interface,
such as a 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 address.
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, 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 a VLAN interface) as the output interface,
which may have multiple next hops, you need to specify the next hop at the same time.
You can delete only IPv4/IPv6 static routes on the Remove tab.
