[c-nsp] Recommendation for Cisco router with Full BGP Route

[Drew Weaver]

Hi,

I have both ASR 9902 and Arista DCS-7280CR2K-30

Downsides of the ASR9902 for us include:

Not being able to configure the ports in the exact way we need to as far as the integrated switch.
Internet Licensing
Had a really hard time trying to renew support for less than 40% of the cost of the entire router for 1 year. I feel like something went terribly wrong here but I wasted 6 months trying to fix it.
Very expensive for what amounts to a 8x100GE router

Upsides:

If you like IOS XR
If you like netflow and not sflow
It's made by Cisco (... I guess that is still an upside)
I don't believe the 9902 uses a proprietary algo to achieve its maximum route scale.

Downsides of the Arista DCS-7280CR2K-30

Sflow only
The OS doesn't seem to know whether or not it has written files to the filesystem when you save a running config or copy a new software image.
The OS doesn't seem to track whether the disk is still working or not. 
I'm not 100% sure I trust flexroute yet for large tables above 1M routes but fingers are crossed.
if you want flexroute you have to make sure you get the K model 
If you don't like EOS

Upsides:

30 ports of 100GE that can break out however we want
If you like EOS
As far as I know there is no phone home or licensing restrictions
I'm not sure on current pricing but these weren’t as expensive as an ASR9902 and you get 22 extra ports.

Thanks,
-Drew

Hi all,

I am looking for recommendations on a Cisco model that meets the following requirements:

- Supports 4 BGP peers (both eBGP and iBGP), each with a full BGP table for IPv4 and IPv6
- Smallest possible physical size (2U max if possible)
- Prefer perpetual license
- Relatively stable CPU usage, preferably ≤50% for most of the time while handling this BGP load

Thanks in advance.
