Hi, I have installed 7.1.3 to CRS318-16P-2S+. I tried to setup the L3HW interVLAN routing based on the website documentation. I think it doesn’t work because I always got high CPU percent. Is it possible on this device? (I tried to enable l3hw on the ether1 also, but doesn’t work…) best regards,…

Doesnt it support it in 7.2rc2? Nope, explained here: https://help.mikrotik.com/docs/display/ROS/L3+Hardware+Offloading#L3HardwareOffloading-L3HWDeviceSupport I have read that document, but I still dont understand. To my understanding, it should be able to? I also read http://forum.mikro…

hi, CRS328-24P-4S+RM, after reboot device no load default route to hwl3. Route is in routing table with mark DAoH but not function. After off/on /interface/ethernet/switch set 0 l3-hw-offloading default route is function. Same with CRS326. With the CRS326, this happens after a few hours of operation…

i believed CRS 328 is not supported, please check your hardware if supported https://help.mikrotik.com/docs/display/ROS/L3+Hardware+Offloading#L3HardwareOffloading-L3HWDeviceSupport

Thanks hapi, the same problem is reproduced in our labs and we look forward to fixing it in future RouterOS releases. No release date available at the moment.

If it helps. OSPF is used. Thank you for your effort. HW L3 allows you to plan own network in a different way.

We have found a few semi-severe issues on 98DX2xxx/98DX3xxx switch chips (CRS305, CRS318, CRS328, etc.) when L3HW is used together with dynamic routing protocols (OSPF, BGP). Most of the issues have already been fixed in v7.2rc5. The remaining ones will be fixed in the next version. Unfortunately, f…

Routes received via BGP were not properly installed to switch chip on CRS328-4C-20S-4S+ with 7.2rc5. Symptoms: establish a BGP session, connectivity is normal enable L3-hw-offloading, connectivity still normal restart BGP session, connectivity is lost until L3-hw-offloading is disabled. Is th…
