Extended LAN networking 

Recently, the term extended LAN networking emerged to represent the
technology used for connecting LANs across extended distances.  The
growth of PC and workstation LANs has been largely responsible for
subsequent growth of extended LANs.  HP's extended-LAN solution is based
on the HP Remote Bridge and HP Routers.

HP Remote Bridge 

The HP Remote Bridge combines two geographically dispersed LANs to form
one common extended LAN. You can use multiple HP Remote Bridges to link
multiple LANs for an enterprise-wide extended LAN. The HP Remote Bridge
is a cost-effective and high-performance way to interconnect remote LANs
over 56-Kbits/DDS or T1 transmission links.  The HP Remote Bridge can
also be managed by the HP OpenView Bridge Manager for DOS.

HP Routers 

The HP Routers allow you to build extended LANs by connecting multiple
LAN subnets.  These subnets can be located at single or multiple sites.
The HP Router is a multiprotocol router that supports many network-layer
protocols, including ARPA IP, Novell IPX, Xerox XNS, and DECnet Phase IV.
For those network-layer protocols that the HP Router does not support,
datalink layer bridging and spanning tree protocol support are available.
In addition, the router supports Simple Network Management Protocol
(SNMP) for network management.  The high-end HP Router supports up to
eight LAN connections and eight WAN connections for a centralized site.
It supports WAN connections through the use of public or private X.25
networks and private-leased transmission facilities.  The high-end router
supports IEEE 802.3/Ethernet connections, 802.5/Token Ring.  The low end
HP Router ER supports two LAN connections and two WAN connections for
connecivity to smaller remote sites.  It supports WAN connections through
private-leased transmission facilities and IEEE 802.3/Ethernet LAN
connections.
