9 ip routing overview routing routers are responsible for forwarding data packets along networks. Upon receiving a packet, a router determines the optimal path based on the destination address. When the packet reaches the last router in the path, it then forwards the packet to the intended destinati...

10 contents of a routing table a routing table includes the following key items: • destination address: destination ip address or destination network. • network mask: specifies, in company with the destination address, the address of the destination network.

14 static routing configuration introduction static route a static route is manually configured, but if a network’s topology is simple, you only need to configure static routes for the network to function. The proper configuration and usage of static routes can improve network performance and ensure...
Page 15
15 while configuring a static route, you can specify either the output interface or the next hop address depending on the specific occasion. For a null0 interface, if the output interface has already been configured, there is no need to configure the next hop address in fact, all the route entries m...

16 detecting reachability of the static route’s nexthop if a static route fails due to a topology change or a fault, the connection will be interrupted. To improve network stability, the system needs to detect reachability of the static route’s next hop and switch to a backup route once the next hop...
