[c-nsp] Cisco Nexus 9300 for CORE

[Robert Hass]

Hi
I need to build new core network. We have 6 site's in different cities. All
cities are connected over 100G (provided by ISP).

I just thinking about N9K-C93180YC-FX and N9K-C93240YC-FX2 switches.
- both supports 6 and 12 x 100G ports which I will use to inter-site
connectivity (core links)
- they supports MACsec on 100G - I will use it to encrypt my core links
- each inter-city link is around 500 miles
- most of downlink ports will be 10G and 1G

Any potential problems with this platform for that purpose ?
Buffers are very low - just 40MB. Maybe I should look at Cisco NCS or other
Cisco platform ?

I'm looking for some experience/recommendations.
