mpls mtu command on subinterfaces

Unanswered Question
Jun 22nd, 2007

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??
