Daniel,
Like Juniper T1600 and CRS-1 I have to agree it will be very difficult
to compare thinking about performance and S.O functionality (ASICs,
Internet Processor 2, Multicasting Matrix Architecture, Hardware Arch,
QNX, Real Time OS, I-Chip ASICs, Forwarding Plane, Control Plane and
Service Plane etc.) ... thinking that major (95 % ?) of the service
providers, telecom companies and research networks (I2, NLR, AARNET,
APAN...) in the world are using something the both trades.
We do not have a lot of other companies cases to show.
Juniper has IPv6 implementation since 10 years ? JUNOS 4.2 ? We have to
agree (too) they have a lot expertise in how it works under mix, heavy
traffic, etc.
Only prices fro this 2 machines are very "HARD" to work !!!
Thinking about Juniper a good suggestion could be the MX Series Family
with high concentration of Ethernet High Speedy Interfaces (SFP).
Cisco CRS-1 is very new, right ? People from NLR (I think) is using the
8 slot router with the new IOS XR based on QNX ... Maybe some of them
could tell how it works under heavy conditions of traffic, v4+v6 mix
with multicast, unicast and MPLS VPNs .. all running togheter.
Thanks,
Giuliano

But a CLI/config as modern as a grammophone. If only they would
copy JunOS instead of IOS... sigh.
But ... I never saw it under extreme conditions with IPv6 ...
They already fail at light conditions, given that there is no
multitopology IS-IS. This equals to "showstopper" if your network
uses multitopo IS-IS for v4+v6 (and perhaps even for unicast and
multicast).
Best regards,
