Can we applied QoS policy on Router sub interface.

[raut.pawan]

Hi ,

I have WAN router where we have single MPLS link from service provider. I have 4 differant vrf configured on that MPLS link.

Gi0/0 - Physical MPLS link

Gi0/0.1 -  sub interface in VRF1

Gi0/0.2 -  sub interface in VRF2

Gi0/0.3 -  sub interface in VRF3

Gi0/0.4 -  sub interface in VRF4

Can I configured 4 differant QoS on these 4  differant subninterface which are in differant differant VRF.
