      I would not like to punt another vendor's equipment but have you looked
at the MX-480 or MX-960. You would not have to worry about CPU
limitations and it is an Internet core box capable of handling all the
protocols.

We're running several six 65xx Sup720-3BXL with 3 full transit views and
some 40-odd peers.  We use two NPE-G1s for reflectors and some policy
manipulation.  Also running MPLS in the core to allow for traffic
engineering and EoMPLS between certain services located in different
locations.

We're pushing up to between 800M and 1G at peak times (mostly outbound)
with this setup and peak CPU on the 3BXLs is running maybe 30% --
average
though of around 8 to 10%.

Hope this helps....

side-note:

I'm actually more worried about the distribution layer at the moment as
it
relies heavily on STP and HSRP/GLBP for the various vlans and access
layer
gunk.  Currently these are 720-3B (non-XL), but looking eventually to
build a business case to upgrade these to VSS1440 to simplify the
architecture as well as providing better resilience and elimination of
STP/HSRP/GLBP limitations between the dist and access layers.  Problem
is
the budget side of that... blargh!

Ideally I'd like to go more for the Nexus platform for this part of the
network, given that we're doing a lot of virtualisation etc., but the
downsides with that are primarily the COST of the bloody things, and
secondly the fact that they don't currently support MPLS (planned for
later this year, apparently).

Moving the BGP to the 12008's would be my choice with PRP-2 processors
if the budget fits.... we're faced with a similar upgrade next year
possibly moving BGP from a pair of 7606's (Sup720-3BXL) over to a pair
of GSR's running PRP2 I think - the BGP processing etc. is pushing the
CPU's too high on the 7600's....
Someone else might suggest the RSP720's but haven't had them in a
production environment yet...  we had PRP2's running on 12012 for a
while and found them rock solid even with older line cards etc...
Hope this helps a bit...;)

We ran into a similar quandary and have about the same amount of traffic
as your 
network. When purchasing gear a year ago we decided against 7200's with
an 
NPE-G2 as insufficient for the load.  Have you looked at the 7304?

The Cisco 7304 with an NSE-150 processing engine on it offloads a lot of
the 
packet processing to dedicated hardware, and doesn't have TCAM
limitations for 
routes. You can hold several full feeds and do the amount of traffic
you're 
talking about without breaking a sweat.

http://www.cisco.com/en/US/prod/collateral/routers/ps352/prod_bulletin09
00aecd8060aac5.html

It is capable of supporting both legacy port adapters (from your Flexwan
or 7200 
routers) and SPA cards with the right add-in modules, which IIRC is only
a few 
hundred dollars.

I'd be glad to answer any questions you have about our implementation.

Cisco 7304 may not adequate for service provider.
It's CPU/IO-controller is tied together, and doesn't provide much of
benefit.

Cisco 7200/7300 is enterprise solution pretty much, and doesn't support
distributed CEF.

If you are considering SUP720-3BXL, why not considering RSP720-3CXL ?

I would love to use the RSP720-3CXL, but cost and the PA OC3 are the
difficulties.

If the RSP720s will run in a 6500 chassis, great! We wouldn't have to
purchase new chassis and the increased downtime for the swap-out.

RSP720 don't support the older bus-only FlexWAN either with the OC3 PA
we're using, so we'd have to figure out a solution for that - SIPs,
Enhanced FlexWAN, or external routers. Bah.

...the RSP720s + chassis + OC3 solution more than double our $20k/node
budget, so that's a much tougher sell internally.

This is, indeed, already happening.  In fact, I'm running an SMTP server

We use Cyclades (avocent) devices in our data center. They have worked
great for us. Very reliable. Modem dial-in gives us great remote
capabilities if we have a major outage. We had troubles initially
getting them to work because the cable adapters were never pinned
correctly for Cisco. We ended up making our own rolled rj45-rj45 cables.
IIRC, this was a ton of work as you need to do some funky 2 wires in one
position stuff. 

We also use Cisco 2500's with modem on the aux and an octo-cable for the
devices. This works well too, but not as nice of an interface as the
Cyclades. No special cables needed though.

For power we have been using APC Managed PDU's. These have been
fantastic. No compaints.

Subject: Managing your network devices via console

Hello,

It's always cool to have console access to routers/switches and nowadays
they are going from RS-232 to RJ-45 as a standart. I have got Avocent
DSR 2035 which is a KVM+Serial console (all in one).. but while I was
able to have it work against servers via KVM or/and Serial , I was
unable to make it work properly against any network device. I am
wondering if anyone had experience on DSR or similar boxes to configure
them against network devices console ports.

Making suggestions for alternative ways of centralizing network device
console management is also more than welcome, I guess the old fashioned
server attached usb-serial console is one of the most preferred way, but
feel free to provide if  you have good ideas

cheers
