Are you just hard coding it on all the interfaces in the Mikrotik…or just the backhaul path's and Telrad Enode’s? Cheers,

Are using 1900 for Layer2 and 1600 for Layer3. If I remember correctly, you need 1580 Layer3 if you want to set your UE’s to 1500 which is what we are trying to achieve.

We use Mikrotik Cloud Core’s L3 routing with OSPF. Wondering if there is any merit in switching the default L3 MTU of 1500 to 1580 for better performance and possibly solve some weird VPN problems for customers on the LTE platform. I know quite some time back there was a number of discussions around MTU…I can’t seem to find them. Currently we are L3 MTU of 1500 and L2 MTU is 1580, some are 1588…. Seems to be calculated automatically. Cheers, Andreas Wiatowski, CEO Silo Wireless Inc. 519-449-5656 x-600
