Proper interface configuration cisco routing
Posted on 2004-10-20
I have a cisco router with 1 fast ethernet interface.
I then have that interface goto a switch, which connects to our bgp peer uplinks.
The question is as follows:
Do I 1. create sub interfaces on the cisco router, or 2. create secondary addresses to connect to the other subnets?
I'm pretty sure that you only want to use sub interfaces with vlan'ing, but I wanted to double check.
