mpls mtu command on subinterfaces

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??

interface GigabitEthernet4/0/1

description MPLSRBGOPE02: phy.Link to MPLSRBGOSwi02 (Gi4/0/1-Trunk)

no ip address

load-interval 30

shutdown

negotiation auto

mpls mtu 1512

interface GigabitEthernet4/0/1.190

mplsrbgope02-test-76(config)#interface GigabitEthernet4/0/1.190

mplsrbgope02-test-76(config-subif)#mpls mtu ?

<64-1500> MTU (bytes)

mplsrbgope02-test-76(config-subif)#mpls mtu 1512
