Juniper MX80 chassis currently deployed in GTS labs do not support HQoS configuration on user interface, i.e. on gigabit ports. Therefore, separate lab scenario was built consisting of Juniper MX104 and Juniper MX10 chassis with MIC-3D-20SFP-E line cards with HQOS support;
No VLAN tagging was used on user ports toward lab-test hosts;
MPLS LSPs are established over gigabit ports instead over ten gig ports as was the case in GTS lab.
