We don't run very much Cisco gear (none of their larger, hardware
stuff) but I have a couple questions for the Cisco gurus out there...
According to this page:
http://www.cisco.com/en/US/prod/collateral/switches/ps5718/ps708/product_data_sheet09186a0080159856_ps4835_Products_Data_Sheet.html
The Cisco WS-SUP720-3BXL can hold "1,000,000 (IPv4); 500,000 (IPv6)"
route entries.
1) Does that mean a) The card can hold 1m IPv4 routes --OR-- 500K IPv6
routes or b) 1m IPv4 routes --AND-- 500K IPv6 routes?
2) I'm assuming MPLS cuts into the number somewhere but could anyone
explain it briefly?
3) Do ACLs use some of these resources or do they get their own slice
of memory?
That page also reports "up to 40 Gbps per slot of switching capacity;
720 Gbps aggregate bandwidth".
Is the 40Gbps per slot an aggregate or full-duplex value?
Thanks for helping out a Cisco n00b!

We use the 7600 platform as a Customer Border device. It attaches
directly to our core, and directly to our customers. This has been a
solid platform. Before this we used to use the 7600 as a load balancer
for a DNS cluster. Worked fairly well. We use the 6500 series for our
main network infrastructure and to border/core/dist layers and they
are
rock solid, as long as you stay away from the SXH images. These are a
bit buggy and we have had routers crash due to that image. We have
deployed a few new devices with the SXI and are very happy with them
currently.

I have an opportuniy to put two 7609s into the core of my network.
Currently we have 3 upstream providers, taking full BGP routes. (2
in one
router and one in another). We have 17 BGP peers/customers (peering
to each
router), and adding about one new BGP peer every 2-3 months. It is
a modest
network by most standards. We are running OSPF and BGP between the
existing
routers.
Not rocket science, nothing special (no MPLS, no VRF etc), very
simple
network.
Does anyone have any recommendations on the 7600's as a core BGP
router?
Good or bad? Have they been a stable platform in a core/BGP
environment?
