I thought that as soon as you turn MPLS on the flow mode was diabled and you were back to good old packet mode?

Ditto, I was writing basically the same email when I saw your post come
through. I got a set of 2350's out of the box running 60% memory
utilization, I added a l3 vpn (with 3 routes) and the nice green bar in the
web interface changed colors on me.

Thanks,

Jay

I know alot of us here have been bitten by this, and the fact that disabling
flow mode and
reverting to packet does not free up any of the ~ 460MB or so being eaten by
fwdd/flowd is
insane.


I am currently having the "This is a design feature, the pre-alloc is
planned" argument
with a SE.


I have no issue with flow features being added, looks great for branch
office use.


What is killing be is that flow is not wanted, needed or usable in a
small-infra use with
multipath and MPLS services, but even disabled flowd is eating half the box
memory.


52% memory usable at bootup (bare config) is not sane, and a 1GB 6350 used
to be able to
handle a few thousand igp routed plus a full table with easy and lots of
headroom, now it
is at 92%....




I am pushing this w/ account team and support case, please do the same.  If
enough people
complain about the insane resource consumption they might actually fix it.
