Juniper is pretty big, and probably the company most of the Cisco users are turning to, in my experience. Cisco has stagnated for so long and continue their attempt to push over prices solutions that simply isn't as good or modern as those of their competitors.

We continued to buy Cisco for longer than we should have, because "New stuff is surely around the corner", but it's not. Cisco still makes enterprise equipment that can't do IPv6. So we switched to Juniper three or four years ago, and may of our customers are doing or considering the same.

Cisco isn't the dominate play it used to be and is almost never the first choice for new projects anymore.
