The Omni Switch/Router
Hardware Routing Engine (HRE-X)
The Omni Switch/Router Hardware Routing Engine (
HRE-X
) is available for the
MPX
and all
Omni Switch/Router switching modules. The
HRE-X
is a submodule, which plugs into an
Omni Switch/Router module, that provides high speed Layer 3 distributed routing for
IP
and
IPX
traffic. The
HRE-X
intercepts frames from the switching logic and determines if a frame
should be switched or routed. If a frame needs to be routed, the
HRE-X
will automatically add
the appropriate routing information.
MPX with an HRE-X
The
HRE-X
has the following restrictions:
• You must have Release 3.4.4 software, or later, on your Omni Switch/Router.
• Do not install an
HRE-X
on an
MPX

• Do not install an
HRE-X
on a
GSX-FM/FS-4W
