Hi All
I know I have seen this question posted before, and have seen various
responses, I just wanted to check if anything had changed with advice.
We are upgrading our network to accommodate 100Gb, and are replacing
our existing Cisco infrastructure, whilst investigating this we have
been seduced with the power vs capability of the Juniper vs Cisco
Question. For us this is between Juniper MX480 / 960 Premium models vs
Cisco ASR 9006.
My question is twofold – What are other people using, and have you got
any gotchas to keep an eye out for, and, are we missing any other vendors.
We've been running the 8-slot Cisco CRS-X since 2014. The box supports a
4x 100Gbps line card, which if you buy via Cisco, can come to nearly
US$200,000 for a single line card + the FP. We deployed a few in 2017,
but when we needed more, this price quickly became unpalatable.
So we went for the PTX1000 instead. 2U box (not the half-rack the Cisco
routers), significantly less power, and 24x 100Gbps ports per chassis.
Looking at where the tech. currently is, we did not feel that going for
yet-another super large chassis-based system to get 100Gbps ports made
sense. The PTX1000 is a bit old, but for us, it is priced right and does
everything we need. As a pure core node, we don't need it to be any
cleverer than it currently is.
The PTX1000 boxes have been solid, save for an LDPv6 issue we are
working on with them.
For the edge, we went with the MX10003 to, specifically, serve customers
that require 100Gbps IP Transit services. We found this to be cheaper
than loading up our MX480's with a bunch of MPC7E line cards for the
same purpose. So we keep the MX480's mainly to aggregate customers
buying N x 10Gbps services or slower.
Mark.
