In order to route between 2 subnets, you would need some device to do the vlan trunking for you. &nbsp;If the router only supports one vlan, then I dont believe it is possible without having another device to do the trunking and routing between.<br />

As for reseting the router to factory defaults, you should reboot the router with console access. &nbsp;Press control-break in the first 5 seconds or so, then you should be able to issue the &quot;erase startup-config&quot; command to clear the saved configuration. &nbsp;Reboot and you should be at defaults.

I am trying the setup basic routing between 2 networks on my 850 cisco router, i know i have to do something with vlans. The router I know has a vlan setup and i know this is the only one that the router can hold<br />
<br />
so firstly, is what i am attempting achievable?<br />
if so, how do i configure the vlan to work.. i want to route between a 192.168.100.0/24 network and 192.168.200.0/24 network<br />
<br />
also for a note of reference , if someone can tell me how to reset the router to factory defaults that would be cool, so i can start a fresh

Cannot assign IPs on a cisco 850 router

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.

Routers

Networking hardware includes the physical devices facilitating the use of a computer network. Typically, networking hardware includes gateways, routers, network bridges, modems, wireless access points, networking cables, line drivers, switches, hubs, and repeaters. But it also includes hybrid network devices such as multilayer switches, protocol converters, bridge routers, proxy servers, firewalls, network address translators, multiplexers, network interface controllers, wireless network interface controllers, ISDN terminal adapters and other related hardware.
