Can someone provide a bit of substance on the reasoning behind using these various methods of creating networks on a router?
I've often seen routers configured that have an interface configured with the 'secondary' command to add additional networks (additional IPs to be used as gateways) when it would seem that a sub-interface (or VLAN interface) would have done the trick. What are the differences in these configuration methods and some of the reasoning behind them?
Thanks in advance!
