Branch Office Routing
"Instant-On" Branch Office Router Installation
Hardware Designed for Branch Offices
Every HP router, from the HP Router ER to the recently announced HP
Router 650, have the following features to enhance remote support:
Software preloaded in flash EEPROM memory. No disks to get lost,
misplaced, or fail. The software is always loaded, and it can be
updated over the network.
Absolutely no hardware configuration options. Hardware can never
be misconfig-ured. All configuration options can be controlled
remotely through software.
Automatic interface detection circuitry. HP routers automatically
detect the type of WAN interface being used. To upgrade an
interface from RS-232 to V.35, merely replace the cable; all HP
routers have circuitry to support all of the commonly used physical
interfaces, and HP routers automatically detect what type of inter-
face is being used. Again, no switches to set, no configuration to
change.
Software Designed for Automatic Branch Office Installation
Dynamic link configuration and SmartBoot help speed the installation of
branch office routers and eliminate costly and time consuming configuration
errors.
Dynamic Link Configuration
In the fall of 1993, HP introduced dynamic link configuration for wide area
interfaces using leased lines. With dynamic link configuration, leased-line
interfaces no longer require the configuration of data-link-layer parameters.
When two routers are connected to an operation-al link, the routers automat-
ically negotiate all link parameters and establish a connection. While the
connection is being established, the link speed is automatically determined.
Transmit queues are automatically configured based on the link speed to
minimize latency and improve application responsiveness.
Dynamic link configuration works not only on router-to-router links but also
on router-to-remote bridge links. This is especially useful when connecting
HP Remote Bridges in branch offices to a router such as the HP Router 650
in a regional or corporate office.
