Foundry's NetIron Layer 3 switch boosts Layer 3 routing performance and eliminates network bottlenecks with wire-speed, multi-protocol routing. Enterprises can use Foundry Layer 3 stackables to build high-performance backbones that provide efficient support for unpredictable intranet traffic. NetIron delivers 10, 100 and 1000 Mbps connectivity. NetIron Layer 3 switch supports standard protocols such as IP, IPX, RIP, AppleTalk, IGMP, DVMRP, PIM-DM/SM, MSDP and MBGP. This broad range of routing support delivers seamless operation to any network. Built to provide consistently high network performance, Foundry Layer 3 stackable switches accelerate Layer 2 and Layer 3 functions in hardware where forwarding, topology management and switching are all performed at wire speed. Foundry Layer 3 switches support up to 230,000 routes. Support for up to 4000 Access Control Lists (ACLs) allows a NetIron to offload traditional routers of their ACL task, allowing for increased network performance and security.
