IPv4 and IPv6 routing configuration
NOTE:
The term router in this document refers to routers and APs with the routing functions.
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.
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 routing, see H3C WA Series Access Points Layer 3
Configuration Guide.
