Static routes cannot adapt to network topology changes. If a fault or a topological change occurs in the
network, the network administrator must modify the static routes manually.
Default route
A default route is used to forward packets that do not match any specific routing 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.
