1. Pentium IIIs don't have switch chips. Therefore they won't be acting as switches in hardware.
2. Not on the switch chip. But you can of course have VLAN interfaces in software on the router and route between them.
3. It works reasonably well. It works extremely well for the price. It doesn't have the same level of support, roadmaps, documentation, and warranties as other enterprise vendors. It costs a fraction of those vendors. That is your trade off.
Hi fewi,
1. So I have to buy RouterBoard that include switch chip for switch feature, even inter VLAN routing ?
3. What environment are you using RouterOS ?
Thanks !!
