hi,
i have a 7604 router with som gig interfaces.
i have some subinterfaces (802.1q) interfaces on the physical interface, which are trunks to other mpls pe router, so i have to do labelswitching.
therefore i use the command "mpls mtu 1512".
the problem is, that i only can configure this command on the physical interface and NOT on the subinterface.
or is it so, that if i configure this on the main/physical interface that automaticly this is also so for the subinterfaces??
