Hi,

You should be able to set the MTU on the xconnect if you have "Per
Subinterface MTU for Ethernet over MPLS (EoMPLS)" feature in your IOS,
try the following;

interface GigabitEthernet6/1.100
description IP Downlink to customer
encapsulation dot1Q 100
xconnect x.x.x.x 100 encapsulation mpls
 mtu 1500

FYI this does not enforce the MTU setting on the data plain however it
should allow you to xconnect to other interfaces with differing MTU's.

Kind regards

James
