Cisco
calls the "MSFC/PFC" modules for the supervisor engine. It
performs
silicon based L3/L4 services, rather than MSM CPU/CEF based forwarding. It is true that there is IOS based LB, which can be enabled on
the
MSFC. However, the functionality is a subset of the LD. You'll have to visit Cisco to get the full scoop on the 6xxx futures for LB. You might forward this to the NANOG list, since I'm a "listen
only"
member. As a disclaimer, I work for Cisco. Thanks! ... Erik --- Erik Murrey "Roeland M.J. Meyer" <rmeyer () mhsc com> wrote on Saturday July

capability
in the 6509 MSN router module?Stephen Sprunk: Friday, July 07, 2000 5:46 PM If you are using a LocalDirector with a Cat6k switch, you
can
enable the Accelerated Server Load Balancing feature. This allows theCat6k toforward the bulk of the flow (at wire speed), and lets the
LD
focusexclusively on the connection setup/teardown functions. For more information:

They doabout 180mbps over3 locations and were running performance problems. (Theyended upmoving toF5's). One of Exodus's Senior Network Engineers has seenthatconsistenlybecome problematic at about the magic 80mbps you
mentioned.
I spokewith afew different neteng buddies when we started looking at
LB's
over ayear agoand they all told me to stay away from the LD's. But likeall of us, theyget better as they stay around longer... Probably, it's the same with all LB products ... you haveto match the rightproducts with your needs. Me, I have to go for the bigscale. So I'llsacrifice features for ability to consistently handle thetraffic andscalability. I eliminated quite a few simply because theycouldn'thandlethe volume, but that doesn't mean that they would work
well
