Static Routing Principles and Configuration

1, 1.1 host to send data to another host 4.1;

2, router A receives the data and check the destination address of the packet, and then checks its routing table;

3, router A forwards the routing table entry according to the inspection data to the interface S0

4 , router B receives the packet and check the destination address and its own routing table to check;

5, router B forwards the routing table entry according to the inspection data to the interface E0;

6, 4.1 host receives a packet via the interface E0;

7, route table and routing table is formed:

the routing table is divided into the non-linear network segments directly connected network segment.
(1) directly connected segment: segments with their directly connected.
(2) non-directly connected network segments: routers and other network segment that they are not directly connected.
8, static routing features;
static routing is generally small-scale local area network use, such as hospitals, factories, office buildings and so on.

9, the default route characteristic;
generally used in the distal network usage, for example, our own home client is equivalent to a stub network.

10, each router is an interface different network segments, among different broadcast domains;

11, static and default routing configuration;

(1) Static Routing Configuration: input ip route network (network number) mask {adrdress (next hop) | interface (Interface)}.
(2) Default routing configuration: input ip route 0.0.0.0 0.0.0.0 address (next hop).
