Hi,

I recently bought a RB450G and am very pleased with it.

Initially I was looking for a CISCO Small Business SRW2024-K9-EU - SG 300-28 - 28-port Gigabit Managed Switch as a center piece for the network, being interested in the L3 routing capability for doing Inter-VLAN routing at wirespeed.

But after my experience with the RB450G I've checked out other products and found the CRS125-24G-1S-IN Cloud Router Switch, which would be more interesting to me that the beforementioned CISCO L3 Switch.

My question is the following: Can the CRS125 do wirespeed Inter-VLAN switching without the need of assigning ports to the full blown router, so that the Inter-VLAN routing is performed by the switch chip itself and not by the AR9344?

I'd like to use only four ports of the CRS125 for mangled/firewalled routing (and so replace the RB450G), and have the rest assigned as switchports with a couple of different VLANs.

Kind regards,
Daniel

L3 routing in hardware is not supported on the CRS.
All routing has to go through the CPU.

If the chip in the CRS can do HW routing, and if its a feature that will come in the future, maybe someone from MikroTik can tell you.

Thanks for the reply.

I was checking the RB450G Switch Chip features, where there is an indication that the Atheros8316 used in that board has a "Rule Table" which "is very powerful tool allowing wire speed packet filtering, forwarding and vlan tagging based on L2,L3,L4 protocol header field condition".

The RB450G is set up as follows:
port 1 = internet gateway in subnet 1
port 2 = subnet 2
port 3 + 4 = bridged in subnet 3
port 5 = unused

Is it possible to use the 5th port as a trunk target, using the rule table of the Atheros8316 on that port to do wirespeed Inter-VLAN routing? This 5th port would not be used to route to other ports on that router. Only on that trunk, a router on a stick.

In that case I would consider getting a TP-Link L2 Managed Switch instead of a CISCO 300 Series switch. Would that yield a similar performance? Using the 5th port of the RB450G together with a TP-Link L2 Managed Switch instead of just a CISCO 300 Series Switch with L3 routing enabled?

Kind regards,
Daniel
