Please can you provide me information about differencess between those 2 modules, considering MPLS support. I am interested in VPLS feature support. Is this new ES20 card support non H-VPLS, like situation where we have access or trunk (dot1q) port on same 7600 router on WS-X6724 SFP card where is MPLS uplink realized with this ES20 card. Generaly,which card OSM or ES20 is better solution for MPLS (L3VPN, EoMPLS and VPLS)feature.
