Hey Dmitry,
> What do you think about Arista 7280SR (DCS-7280SR-48C6-M-R) as a BGP peering router with 3 x upstream with full route view in RIB (ipv4 + ipv6) and another IXP feed?

You should compare 7280SR against NCS5500 and PTX1k, not ASR and MX.
ANET is great company, with great people, but they are like 2 years
old in SP market and this is quite visible. It is impressive though
what they've done in so little time.
Check out the 7280sr2k, which is actually 24*10G, 24*25G, 6*100G
Thanks for info!
We have been using the 7280SR-48C6 for 2.5 years now. Just after Arista announced the full table BGP routing.
Looking at the price / port there is nothing near Arista. We also use Cisco ASR1K and Juniper MX204 but these have far less capacity.
When we first started, there were quite a few features missing but over the past 2 year they have really been catching up. I was very happy when they added MSS clamping at the end of last year.
The new version 7280R2K should be able to handle 2M routes.
It would be worth your time to look at Extreme SLX9640 with advanced routing license.
How much do these boxes cost?
Is there any reason to have 2M routes support for next 3 years?
Full IPv4 table + full IPv6 table + multiple VRFs (BGP-VPN, etc.) plus lots of on-net deaggregates could well push you above 1M right now especially if your platform also shares that "1M" FIB space with next-hop L2 information, ARP/ND entries, etc. Bonus points for neeing MPLS info in FIB, too, on MPLS PE routers.
IPv4 DFZ alone is rapidly growing to where it'll hit 1M for most viewpoints without FIB compression, though most end networks can probably compress it down a fair bit from that.
2M is the next "logical" FIB scale to target, I guess. I've seen 1.5M boxes, too, though the headline FIB scale is always suspect. You have to look at how other things that sit in TCAM will eat into that scale, whether it has static or dynamic CAM partitions, etc.
List is about $100k in North America for a 9640 with all the ports "unlocked", full hardware kit (PSUs, fans, etc.) and some maintenance/support. Take whatever your standard Brocade/Extreme discount from that tends to look like. I should hope nobody pays list or anywhere close.
Agreed.
So how does the 7280SR-48C6 compare to the SLX9540? They are the same Broadcom chipset right? So the real question, is how does the product differ in software?
I think a 9540 would compare more directly against a Nexus 9k series device. They're targeted more at datacenter switching but have full L3 + MPLS and some features useful for carrier applications as well.
I just realized that the 7280SR is an Arista device, not Cisco. Argh...too many similar model numbers.
I haven't used Arista much at all really.
We are currently swapping out our Juniper EX4550's and EX4600's for
Arista's 7280SR switches, but this is purely for Layer 2 Ethernet
customer aggregation in the data centre.
The main issue we are having is getting support for L2PT in the Arista
on par with what Juniper and Cisco can do today. So far, some of the
critical protocols are trickling into test code, but there is still a
little bit of way to go before we get everything we need.
At any rate, it seems there are no hardware limitations in getting those
protocols implemented, and Arista just need to get more people on to the
code to write it all up. So that's a positive, although it is delaying
our migration.
In the core, been using the 7508E for 100Gbps Layer 2 Ethernet
aggregation for over a year now. Apart from some fabric modules that
failed in 2 switches at the same time (nothing really major as that is
part of network operations), they've been solid.
Mark.
