Is there any particular reason why those switches have MIPSBE CPU as opposed to dual core ARM in CRS317 and CRS309? I mean well CRS317 and CRS309 may not be best routing performers but 3gbps, with 9k jumbo probably much closer to actual 10G is not too shabby for simple inter-vlan routing or uplink routing.
While CRS312 and CRS326-24S+2Q+ basically have CPUs that allow them to... run RouterOS instead of just SwOS I guess? Comparing to switching capacity of those devices 800mhz MIPSBE will do what - 1gbps routing? Okay for CRS326-24S-2Q+ I guess it doesn't make sense to put any reasonable CPU since anything to match its switching capacity would probably cost more than whole this switch but CRS312 doesn't sound THAT powerful tbh. It actually has lower capacity than CRS317. So idk it could make use of some dual core ARM probably.
I'm mostly bringing this topic up since for a while it looked like you guys are slowly heading towards L3-ish switches but now it went back all the way to CRS2xx series with ultra-poop CPUs incapable of any decent L3 processing. Not that I have problem with router-on-the-stick configurations for inter VLAN routing but you're still somewhat limited to uplink speed (which is not a problem for CRS326 with 2x 40G uplinks but for CRS312 it's not so cool). It's kind of like gigabit CRS326-2S+ where lack of routing is non-issue since you have 20G uplinks and 24G access ports so it's totally fine and for new CRS326 it's 80G uplinks for 240G access ports so quite fine I guess but then again you don't have routers that could easily handle 80G of simple inter VLAN routing (except CCR1072 maybe but it's probably overkill for simple inter VLAN routing) while 20G with jumbo should be easily doable on any 2S+ CCR.
I'm basically confused by L3 inter VLAN routing options because your gear doesn't seem to have capacity to bring inter VLAN routing at any decent performance to network using CRS326-2Q+. In matter of fact I don't see any option AT ALL to provide inter VLAN routing to CRS326-2Q+ because even other vendors assume that at this speed inter VLAN routing is performed on L3 switch and any routers with QSFP+ interface will be some hardcore carrier grade behemoths handling such traffic with all bells and whistles. Well there's always just option to get generic server with 40G QSFP+ network card and do such simple jumbo frames routing on budget Linux box but well... it's kinda ghetto tbh.
Does anyone else see some other reasonable way to provide inter VLAN routing to CRS326-2Q+?
