IPv4 and IPv6 routing configuration
Overview
Upon receiving a packet, a router determines the optimal route based on the destination address and
forwards the packet to the next router in the path. When the packet reaches the last router, it then
forwards the packet to the destination host. Routing provides the path information that guides the
forwarding of packets. Routers are responsible for routing packets on the Internet. A router selects an
appropriate route according to the destination address of a received packet and forwards the packet to
the next router. The last router on the path is responsible for sending the packet to the destination host.
A router selects optimal routes from the routing table, and sends them to the forwarding information base
(FIB) table to guide packet forwarding. Each router maintains a routing table and a FIB table.
Static routes are manually configured. If a network’s topology is simple, you only need to configure static
routes for the network to work properly. 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.
NOTE:
For more information about routing table and static route, see H3C WX3000E Series Wireless Switches
