FOUNDRY NETWORKS AND IP INFUSION WORK TOGETHER TO DEVELOP IPV6 BASED SWITCHING AND ROUTING SOLUTIONS

High Performance Networking Solution Provider to Develop Next Generation Routing Solution Including OSPFv3, RIPng, and BGP4+ Routing Protocol Support Using IP Infusion's Routing Software

October 30, 2001, San Jose, CA - Foundry Networks®, Inc. (NASDAQ: FDRY), a performance and total solutions leader for end-to-end switching and routing, and IP InfusionT, a leading provider of advanced network software for the support of next generation network equipment, today announced that they are working together to integrate IP Infusion's ZebOST IPv6 based routing protocols into Foundry's line of high performance Layer 2 - 7 switching and Internet routing products.

The Internet Protocol version 6 (IPv6) is the next-generation Internet Protocol as specified by the Internet Engineering Task Force (IETF). IPv6 offers expanded IP addresses to support the proliferation of Internet devices as a result of the global Internet expansion, seamless mobility support, enhanced security and support for emerging advanced Web based applications.

"We are committed to delivering high performance, end-to-end IPv6 based solutions for our customers, " said Bobby Johnson, president and CEO of Foundry Networks. "IP Infusion's IPv6 network software is the most complete IPv6 routing suite on the market today. Integrating this technology into our products will provide us full IPv6 functionality and allow us to take a key leadership role in provisioning IPv6 networks worldwide."

Foundry Networks is working closely with the WIDE (Widely Integrated Distributed Environments) Project in Japan. The WIDE project operates several major Internet Exchanges, which handle many ISP peering configurations. Foundry will extend their support for WIDE to include a number of IPv6 related projects. This support enables the WIDE project to expand with a robust, scalable, IPv6 routing protocol implementation using IronWareT, Foundry's industry-leading high-performance switching/routing software suite. WIDE has also been an IP Infusion partner and has been implementing IPv6 software provided by IP Infusion in their network for over two years.

"We are seeing a growing demand for IPv6 routing in a broad range of markets, in Japan, Europe and throughout the world," said Nick Keating, president and CEO of IP Infusion. "We are pleased to be working with the industry leader, Foundry Networks, to assist them in developing complex IPv6 switching and routing solutions."
