"There are vendors who are shipping boxes today with 24x1GE and 2x10GE uplink, wire-rate, which can do VPLS and P2P Ethernet/CES, but no L3VPN. However, you can connect into a L3VPN virtual routed interface via a P2P pseudowire. The boxes are cheaper than EX4200s..."
Sounds interesting , care to name vendor/model?
