Alright guys, looking for some help here on getting my configuration setup correct.
Network layout is as such…
Router is a RB493G (willing to buy a new board if need be)
I have 6 vlans. VLAN 1,10,11,12,13,15.
On my 493G I have a cisco switch plugged into ether2. I have all the VLANs trunked from the cisco to the mikrotik and vlans created for each interface, and assigned to a bridge for that vlan. Each bridge has it’s own IP range and dhcp, etc setup.
On ether3 I have a device plugged in and attached to the bridge that corresponds to vlan 1 on the other device.
The problem is I would like to plug more devices into ether4,5,6 but it seems traffic from ether3 that goes across the bridge ends up using the CPU on the mikrotik. This wouldn’t be a huge problem, but a file transfer has managed to get the router CPU to 98-100% for the entire duration of the transfer. I can manage to push around 80-90MBps which is about all that could be expected, but doing this causes traffic to suffer, and if I push two file transfers I have actually managed to crash the mikrotik do to this. I think I set something up wrong, but I’m not sure what or where. Also I see these same problems if I push anything between the vlans that are all plugged into ether3.
To summarize, any decent amount of traffic that goes into the mikrotik and comes back out on the internal side pegs CPU at almost 100%. I can download from my 50Mb internet connection fully maxing it out for hours upon hours and never see CPU go above 25-30%, but internal traffic between two ports on the same bridge, or bridge to bridge kills CPU and sometimes crashes the router.
Can you guys please give me any suggestions as to what my interface setup should look like.
Thanks
