packet routing

By jasonf ·
If I have 2 networks, 195.211.211.0 and 214.202.202.0, and have one router and one switch, will traffic between the two networks ALWAYS pass through the default gateway to reach each other (through the router). Or is it possible the the switch can handle the traffic without the router? Thanks.

packet routing

Hi Jason. I am assuming that your switch is a layer 2 switch here.

Normally, a host on an IP network that needs to send a packet to a host on a different subnet will always try to send the packet to a defined or default gateway. If it has no knowledge of a gateway to the subnet, it will report 'destination unreachable'.

Depending on the OS used, however, it is usually possible to tell the TCP/IP stack on a particular computer that all subnets are local. If you do this to all of your computers, they would be able to communicate with each other without the use of a router. Unfortunately, they would not be able to communicate with any non-local system (such as on the Internet). Hence, it is preferable to use your router.
