Can we take and use Routeros as a layer 3 switch?
Yes I know that routeros can do OSPF, but say I took a 532 board with daughter card so I had like 9 ether ports. and wanted to use it as a switch with vlans and ospf. Make it run like a Full Layer 3 switch?
What kind of configuration do you want to achieve (as it possible to bridge ports, but e.g. OSPF travelling over the network will pass bridged ports transparently).
I’ve worked with several rackmount RouterOS systems that had multiple 4 port ethernet cards in them. Each port had different IP networks configured on it and the box routed traffic between the interfaces and our upstream links. Unless you’re doing something exotic like multicast/IGMP, a RouterOS system is a low cost way to build a L3 switch. You’re not going to get the performance of a Cisco, etc, though, because they route packets in hardware, RouterOS is forced to shuffle them around using the CPU.
