Hi,
In my opinion the 6500 are targeted to big LANs and/or corporate
networks. All the features and modules available on this platform cans
be used in such networks. In our case we have quite old 6500 (Sup720) in
metro network (pure L2 switching). The XMRs we have in WAN (country
wide). We have MPLS running on XMRs.
Some time ago Cisco made some changes to MPLS implementation, but I
didn't test it. However, I think the 6500/7600 has major conceptual
(hardware) limitations - New features requires module replacement
(Supervisor and/or line cards).
The MLX/XMR platform is good for ISPs. At the moment the software is not
so advanced as JunOS, but new features simply comes with software (FPGA)
updates. The platform is more flexible - Foundry assured us that it is
even 100Gbps ready.
So - if you need "feature-rich" platform for corporate network and you
are Cisco centric - it would be easier for you to buy 6500, but if
you're looking for efficient and flexible routing/switching platform
Foundry will be good for you.
From what someone told me I gather the XMR/MLX is more of a router
than a layer3 switch (like the 6500/7600)
Yes indeed - on XMR/MLS you don't have to enable L2 switching. However
it uses virtual interface to make IP subinterfaces.
Essentially what i’m after is just someone who has had good exposure
to both vendors and can give me an honest non biased opinion on what
they like and dislike about the XMR/MLX’s compared to the Cisco offerings.
My summary is - Cisco for corporate LAN and XMR/MLX for WAN/ISP networks.
Best Regards
Tomek
Cheers
Ben

We have 8 in XMR's in production at this point, some running hundreds
of BGP sessions, and our pain has been minimal. There was a pretty bad
software bug that caused us to send full tables to peers so we were
tripping max-prefixes, but it was addressed. I think we've had 1 line
card fail in the past 6 months, so not bad.
I would definitely recommend the XMR for its price/performance point.
However, be very careful with what you try to do with a SuperX :-).
Don't mix SuperX with BGP if you can help it.

Time and time again I've gotten anecdotal recommendations that Foundry
should only be used for layer 2. I would like to open that up to a
wider audience with a perhaps more directed question:
What is there about the MLX platform that helps it compare to the
available offerings from Juniper/Cisco/etc? Why did you end up with
that gear other than just price? With the same options available,
would you buy it again?
(Please avoid the flamable aspects of that conversation)
