Features

HP routers interconnect local and remote LANs (Ethernet/802.3, token ring/802.5, and FDDI) to create extended LANs. They provide both bridg- ing and routing capabilities and support the Internet Protocol (TCP/IP protocol suite), DECnet Phase IV, Xerox XNS, Novell IPX, and AppleTalk Phase 2 routing services. If a packet arrives with an unsupported proto- col, these routers use their bridging capability to send the packet toward its destination. This allows full support for environments where non-routable, uncommon, or unsupported protocols may exist.

On most models there is also one or more synchronous WAN ports supporting RS-232/V/24/V.28, V.35, X.21, or RS-422/RS-449/V.36 interfaces. These provide HP Point-to-Point, PPP, V.25 bis, SMDS, frame relay, and LAPB (X.25) connections to other routers.
