I have two STM4 SDH capacities and one STM16 SDH spanning two cities over different service providers. See Attachment, I have two Cisco ONS 15454 in two cities, one of the ONS is connected to a GSR router serving as core router while the second ONS is connected to a 7609-S serving as MPLS-PE router, their is DOT1q tagging transparently carried over the SDH circuits between the two routers. I want to make these capacities one big Ethernet pipe (10G) at both ends, this fat pipe should be able to carry multiple VLANs between the attached routers at both ends. Is this achievable? if yes what kind of Ethernet cards do I require on ONS and the routers? Any supporting document will be highly appreciated.
