Cant get it running with MPLS MTU 1526
The l2mtu of the interface shows "0" changing l2mtu does nothing.
I can change MTU to 1600. As soon as I do this I get OSPF errors:
route,ospf,info Discarding Database Description packet on ether1 (x.x.x.x): different MTU
So I would need to change all Routers MTU on the same segment to MTU=1600.
