1-2While configuring a static route, you can specify either the output interface or the next hop address asneeded. The nexthop address cannot be a local interface’s IP address; otherwise, the routeconfiguration will not take effect.Actually, it is necessary to identify next hop addresses for all route entries because the router needs touse the next hop address of a matching entry to resolve the corresponding link layer address.Default RouteA router selects the default route when it cannot find any matching entry in the routing table for a packet.If there is no default route, the packet will be discarded and an ICMP packet will be sent to the source toreport that the destination is unreachable.You can configure the default route, an IPv4 static default route has both its destination IP address andmask configured as 0.0.0.0.Configuring IPv4 RoutingDisplaying the IPv4 Active Route TableSelect Network > IPv4 Routing from the navigation tree to enter the page shown in Figure 1-1.Figure 1-1 IPv4 active route tableTable 1-1 describes the fields of the IPv4 active route table:Table 1-1 Description of the fields of the IPv4 active route tableField DescriptionDestination IP AddressMaskDestination IP address and subnet mask of the IPv4 routeProtocol Protocol that discovered the IPv4 route
