Total net recently talked about class Ethernet, the second area Network IP networking experiment is the experiment. This experiment mainly used netsim this router simulation software. Persevering, not on the mac, then we conducted a simulation (in fact, the contents of the experiment) with Cisco Packet Tracer, hoping to get one of these principles more clearly.
It does not involve the use of Cisco Packet Tracer instructions (in fact, easy to understand, learned gauge network should be very easy to get started), the following is a copy of this experiment configuration documentation.

The reality is that the current simulation software UI people are very friendly and most (all) of the configuration can be found button. Effect after the configuration is as follows.
Himself drew a route map.
A typical routing table (here routerC):
After the correct configuration can ping through several hosts, end IP networking experiment.
PS: There is a point of doubt, dg: Default Gateway is the default gateway. Its role and significance in the next essay.
