We have been using Juniper since 2003 and that is definitely _not_ my 
experience. We have used them extensively as P, PE, and Internet Edges 
in a tier 1 regional carrier. (We also have used ASRs in the same 
capabilities). IMO both do Internet Edge well. But I and most of whom I 
know would take an MX960 over an ASR9k any day, the BGP functionality 
and extensions are well developed in JUNOS. Also note that Junipers main 
philosophy and focus is based on MPLS so thats why its dominant in 
carriers for that function.

Cisco do EVPN/vxlan well. They do CE well, (though I'd argue the SRX is 
a good candidate for this too). But they just cant compete against 
Juniper for SP stuff IMO. Same for Arista. That are good in the DC but 
they don't have much carrier market share I believe. Anyway you will 
note my bias leans towards Juniper in the IP routing world.

I find the juniper licensing a bit more upfront and honest too. Though 
with the higher speed capabilities that's eroding somewhat.

MX104's are the dual brain unit of the 204. Though a 204 has 40/100G 
capabilities. If I read your original request correctly about ip 
routing. Not sure the 104/204 is grunty enough to deal with multiple 
internet tables. Thats a demanding task these days best left to the 
larger chassis.

Their policy and filter language is very comprehensive, but very complicated and takes a long time to get familiar with and understand.

Testing has been long and frustrating, and of the 4 platform that I was looking at, all for various tasks, I decided that the only role I’m comfortable having played by Juniper is an MX204 running as a BFD/ISIS/LDP/MPLS enabled peering/transit border router.  So far, it seems to do that *really* well.  However, based on feedback received from people who have been running Juniper for a long time, and reading what folks have been saying here and elsewhere, we feel that it’s just too risky to put this stuff anywhere else.

We’ve just deployed a pair of these for EVPN-MPLS and they’re slick, and from what I understand, they have the FIB scale to be able to act as a border router.  It’s a very IOS-like CLI (but so many things about the CLI are so much more refined than IOS) so it may be more familiar, unless you’re Cisco experience is limited to IOS-XR.  It’s about USD$50K list for 48 x SFP+ /  6 x 40/100G, including licensing.

But, for the number of times I’ve had that kind of failure on any of my boxes that have had redundant cards, I don’t think it’s worth the cost or the rack space, especially if it’s just a border router where you’ve probably got a bunch of other border router that can accommodate a crash or a reboot or whatever.
