Product architecture
• Distributed processing
• Distributed processing
Two kinds of engines are hardware-separated: main controller engine (routing engine) and
service engines (Flexible Interface Platform [FIP] and Service Aggregation Platform [SAP]);
the main controller engine is used for route computing and system management, and service
engines are used for processing services.
• HP Apollo Processor
HP in-house designed service/forwarding processor supporting powerful parallel processing,
encryption and comprehensive HQoS functionalities.
Layer 3 routing
• Static IPv4 routing
• Static IPv4 routing
Provides simple manually configured IPv4 routing.
• Routing Information Protocol (RIP)
Uses a distance vector algorithm with UDP packets for route determination; supports
RIPv1 and RIPv2 routing; includes loop protection.
• Open shortest path first (OSPF)
Delivers faster convergence; uses this link-state routing Interior Gateway Protocol (IGP), which
supports ECMP, NSSA, and MD5 authentication for increased security and graceful restart for
faster failure recovery.
• Border Gateway Protocol 4 (BGP-4)
Delivers an implementation of the Exterior Gateway Protocol (EGP) 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;
scales to very large networks.
• Intermediate system to intermediate system (IS-IS)
Uses a path vector Interior Gateway Protocol (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).
• 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
to an IPv6-only network design.
• Routing Information Protocol next generation (RIPng)
Extends RIPv2 to support IPv6 addressing.
• OSPFv3
Provides OSPF support for IPv6.
• BGP+
Extends BGP-4 to support Multiprotocol BGP (MBGP), including support for IPv6 addressing.
• IS-IS for IPv6
Extends IS-IS to support 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; is an important element for the transition from
IPv4 to IPv6.
• Multiprotocol Label Switching (MPLS)
Uses BGP to advertise routes across Label Switched Paths (LSPs), but uses simple labels to
forward packets from any Layer 2 or Layer 3 protocol, which reduces complexity and increases
performance; supports graceful restart for reduced failure impact; supports LSP tunneling
and multilevel stacks.
• Multiprotocol Label Switching (MPLS) Layer 3 VPN
Allows Layer 3 VPNs across a provider network; uses MP-BGP to establish private routes
for increased security; supports RFC 2547bis multiple autonomous system VPNs for
added flexibility.
