hrm...<br />
<br />
to clarrify, no ip address has to be set on the interface to utilize the vlan features of the sub interfaces, correct?<br />
<br />
Thanks,<br />

... This solution works, but I would rather utilize the subinterfaces, however, the switch connected to the router does not support vlan trunking.<br />

<div class="content wysiwyg-content">
I have a cisco router with 1 fast ethernet interface.<br />
<br />
I then have that interface goto a switch, which connects to our bgp peer uplinks.<br />
<br />
The question is as follows:<br />
<br />
Do I 1. create sub interfaces on the cisco router, or 2. create secondary addresses to connect to the other subnets?<br />
<br />
I'm pretty sure that you only want to use sub interfaces with vlan'ing, but I wanted to double check.<br />
<br />
Thanks,<br />

Proper interface configuration cisco routing

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.
