I have a Router Board 1000 running OS 3.3 and tried to configure Jumbo Frame on L2TP server. Winbox came back with a message that for Max MTU the supported values were between 512-1500 bytes. Ether2 and Ether3 are configured as 1Gbps full-duplex.

The following link gives the impression Jumbo frames are supported on RB 1000. http://wiki.mikrotik.com/wiki/Maximum_T ... uterBoards

Looking for confirmation if Jumbo frame are supported for L2TP Server on a RB1000.
