Features of HP Routers
Routing Services and Protocols
incremental routing updates, and supporting a hierarchical update structure
(using areas).
RIP and OSPF are described in more detail in the "Internet Protocol Routing
Service" note later in this manual.
For connections to external IP networks, HP routers support the standard
Exterior Gateway Protocol (EGP). EGP provides secure connections
through designated routers to external networks.
The IP router software for HP routers provides full support for transport-
layer protocols such as Transmission Control Protocol (TCP), the Internet
Control Message Protocol (ICMP), and the User Datagram Protocol (UDP).
Both ARPA/Berkeley and HP NS upper-layer services are supported, includ-
ing the ARP (Address Resolution Protocol) and HP Probe address resolution
protocols. For more information about HP Probe, refer to the note "A Primer
on HP Probe" in this manual.
Novell IPX
HP routers support the Internet Packet Exchange (IPX) and Sequenced
Packet Exchange (SPX) protocols used by Novell's NetWare. The IPX
routing service integrates NetWare-based PC networks into the enterprise
LAN. The IPX routing service on HP routers is compatible with network
nodes that use Novell NetWare version 2.15 or later. HP routers can
interoperate with routers using Netware and with Novell routers—by
negotiating data-link characteristics when establishing a WAN link (over
PPP, X.25, or frame relay). IPXWAN Version 2 is supported. For more
information about IPX, refer to the "Novell IPX Routing Service" note in this
manual.
AppleTalk
AppleTalk is the protocol suite developed by Apple Computer, Inc., for LAN
communications between Macintosh personal computers. HP routers
support AppleTalk Phase 2, which enhances the original AppleTalk protocol
suite (Phase 1) by expanding the addressing and naming capabilities
previously available. The AppleTalk Phase 2 standard also provides support
for Ethernet and token ring networks in addition to LocalTalk, Apple's
proprietary data-link-layer protocol.
