Version 32.5 adds Multiprotocol Label Switching (MPLS) support on Extreme 7520 and 7720 series switches. MPLS speeds up network traffic. When forwarding packets, the Layer 2 (Switching) label is used to avoid complex destination lookups in the routing table. MPLS uses Label Switched Paths (LSPs) to establish the network path. The packet will be labeled so that service providers can decide the best way to keep traffic flowing.
