Data sheet | HP 7500 Switch Series
• Intermediate system to intermediate system (IS-IS)
Uses a path vector IGP, which is defined by the ISO organization for IS-IS routing and extended
by IETF RFC 1195 to operate in both TCP/IP and the OSI reference model (integrated IS-IS)
• BGP-4
Delivers an implementation of the exterior gateway protocol, utilizing path vectors; uses TCP
for enhanced reliability for the route discovery process; reduces bandwidth consumption by
advertising only incremental updates; supports extensive policies for increased flexibility; and
scales to very large networks
• Policy-based routing
Makes routing decisions based on policies set by the network administrator
• IP performance optimization
Provides a set of tools to improve the performance of IPv4 networks; and includes directed
broadcasts, customization of TCP parameters, support of ICNP error packets, and extensive
display capabilities
• Unicast reverse path forwarding (uRPF)
Limits erroneous or malicious traffic in accordance with RFC 3074
• Static IPv6 routing
Provides simple manually configured IPv6 routing
• Dual IP stack
Maintains separate stacks for IPv4 and IPv6 to ease the transition from an IPv4-only network
design to an IPv6-only network design
• RIP next generation (RIPng)
Extends RIPv2 to support IPv6 addressing
• OSPFv3
Provides OSPF support for IPv6
• IS-IS for IPv6
Extends IS-IS to support IPv6 addressing
• BGP+
Extends BGP-4 to support multiprotocol BGP, including support for IPv6 addressing
• IPv6 tunneling
Allows IPv6 packets to traverse IPv4-only networks by encapsulating the IPv6 packet into a
standard IPv4 packet; supports manually configured, 6-to-4, and intra-site-automatic-tunnel-
addressing-protocol (ISATAP) tunnels; and is an important element for the transition from IPv4
to IPv6
