Features Of Hp Routers - HP 200 Series Services And Applications

Features of HP Routers

Each HP router is a multiprotocol router and multiport bridge. The router is
used to form an internetwork using local area connections (such as
Ethernet, IEEE 802.3, token ring, and FDDI) and wide area connections
(such as leased lines, X.25, frame relay, SMDS, and ISDN services).
This product note summarizes the features of HP's AdvanceStack line of
routers in general. Each specific router product may not support all of the
features described here. For cost-effective branch routing, for example,
some routers in the 400 series have a fixed selection of ports, and routers in
the 200 series have a partial selection of routing services. And for a central
site router, the HP Router 650, port modules allow you to select the types
and number of port connections needed. For the features available and
unavailable on specific routers, see the HP Network Connectivity Product
Catalog, or the installation manual and release notes for your specific router
product.
Routing Services and Protocols
The standard configuration of HP routers supports concurrent operation of
five popular routing services: Internet Protocol (the TCP/IP protocol suite),
Novell IPX, AppleTalk Phase 2, DECnet Phase IV, and Xerox XNS. For
packets that cannot be routed, the router can function as a learning bridge,
source-routing bridge, or translational bridge, and can use the IEEE 802.1
Spanning Tree Protocol.
Each routing service may be enabled independently of the others, and it
builds and maintains its routing database independently of the others. Like-
wise, the bridging service may be enabled independently of any of the rout-
ing services; if not enabled, then the router will drop packets with protocol
types not enabled or supported (such as IBM SNA or DEC LAT). Because of
the independent routing services, the HP router is often referred to as an IP
