I have enabled all my 3750G switches with:


system mtu jumbo 9000


Should I leave the system routing mtu set to default (1500) ?


I am using all gigabit ports. No 10/100 ports.


I read that the 3750 only support like 1998 mtu for routing.


Someone please advise.

If you are using OSPF, I highly recommend leaving it to 1500. OSPF uses MTU for neighbor adjacency.

Correct.
