[c-nsp] Cisco ASR 9K Vs 7600

[Chris Evans]

Andris,

MX's are decent devices, however I would say that the 9K has on-up'ed
Juniper on this.. I have experiences with both platforms and working with
them both, the MX is definitely outdated. However their new Trio 3D
linecards are bringing the MX back into the new-age a bit. I would agree
with your approach of going with a Cisco solution if it is what your company
knows. Support personnel shoudl be one of the biggest concerns.

As for the Nexus 7K, it depends on what you're trying to do.. The Nexus
platforms are SWITCHES not routers. While the newer XL line cards and
software is closing the gap somewhat, it still doesn't change the fact.

The 7600 is still technically a switch in my eyes. Its still based off the
6500 technology, while it has the newer router style ES cards I still see it
as a switch personally. Good platform, just a bit dated.

I believe the ASR9K would be the wise decision. We are starting to ramp up a
project to utilize the 9k's for so data center interconnects to build a
second core between the data centers along with our main MPLS based core
using GSR/CRS platforms. Both platforms have bugs, IOS XR is the path that
Cisco is going for service provider hardware. Another question to ask is if
cost is a concern, I believe the 7600's are cheaper. I am not certain on
that though..


I am going to throw this question out however, assuming you're buying
hardware at this level.. Do you not have a Cisco SE team that would work
with you to help you determine which platform is right for your use?

Chris
