4 HP Router CR, Technical Data Product Numbers 27270A, 27271A, 27272A, 27274A, 27276A, 27277A, and 27278A The HP Router CR is a high-performance, multiprotocol router and bridge. It can be used to interconnect any number of LAN networks to create an "internetwork" which links together LANs on a single site, and/or connects LANs at multiple sites via high-speed links. Highlights o Concurrent Multiprotocol Routing and Bridging: The HP Router CR can be configured to support concurrent operation of five popular routing protocols: TCP/IP, DECnet IV, Novell(r) IPX, Xerox XNS, and AppleTalk II. For packets that cannot be routed, the router can function as an Ethernet/802.3 learning bridge with the IEEE Spanning Tree protocol and/or as a Token Ring (802.5) bridge with the Source Routing Transparent protocol. It can also connect to X.25 networks in a variety of configurations. o Flexibility: By adding the appropriate network interfaces, the router can be configured to support from 2 to 8 LAN ports or a maximum of 16 WAN ports. It can also be used in combination with the HP Router ER and HP Remote Bridge to create cost effective internetworks. o High Performance: The HP Router CR employs a parallel, multiprocesser architecture for excellent LAN-to-LAN performance, even in multiprotocol networks with high traffic loads [Figure: HP Router CR, caption: none] Features o Provides concurrent multiprotocol routing and bridging for maximum flexibility in connecting different multivendor devices on the network. o Offers five standard routing protocols: TCP/IP, DECnet IV, Xerox XNS, Novell IPX, and AppleTalk II. o Operates concurrently as a multiport Ethernet/802.3 bridge with the IEEE 802.1 Spanning Tree Protocol and/or Token Ring (802.5) bridge with the Source Routing Transparent protocol. o Allows connection of Ethernet/802.3 networks to Token Ring (802.5) for networks using TCP/IP, Novell IPX, and/or AppleTalk II protocols. o Supports the standard protocols used for routing table management in multiple router networks: Open Shortest Path First (OSPF) and Routing Information Protocol (RIP). o Supports from 2 to 8 Ethernet/802.3 connections via the standard AUI port. o Supports from 1 to 4 Token Ring (802.5) connections at 4 or 16 Mbit/s via the mini DB-9 connector. o Can transfer data through X.25 public data networks (PDNs). o Supports up to 16 synchronous WAN connections. Different interface cable options provide RS-232, RS-422/449, V.35, or X.21 interfaces. Supports data rates up to 2.048 Mbit/s. o Allows load balancing between multiple WAN links of equal bandwidth. o Allows synchronous traffic from X.25 packet switches and/or mainframe terminal controllers to be integrated with router traffic over one set of WAN links. SDLC, HDLC, or LAP-B data streams can be connected to a 5 synchronous port on the router and forwarded to another router port in the network. o Provides a wide variety of filtering options for network security and isolation. o Supports the Simple Network Management Protocol (SNMP). Works with HP OpenView Network Management Software. Also manageable via the router's console (RS-232) port or Telnet (remote terminal) access over the network. o Supports remote installation of new versions of HP Router CR software over the network using the Trivial File Transfer Protocol (TFTP). o Optionally mounts in a standard 19-inch rack using the built-in mounting brackets.
