Re: Suggestion for Layer 3, all SFP+ switches

Łukasz,

Out of all those Cisco models, which meets the OP requirements of  " (at
least 24) SFP+ ports 10G and at least a couple of upstream ports 40G
capable" and  a " The budget is around 3000-5000 $ each, possibly. "?

The Nexus 7000's look very large with the smallest being 3U in size, so I
doubt they would meet the budget requirement. The Nexus 9000 series seems
to have 1U versions. Assuming he is fine with using Segmented Routing
instead of LDP, any models that fit the bill price wise? Are there any
Nexus products that are lower cost that the Catalyst   (C3650/3850) and
newer (C9xxx)?

The Catalyst UADP based platforms seem nice, but most are requiring DNA
licensing driving up initial cost.

Cisco has mutliple options, but mainly the NCS based on your port count I
think. Supposely the C3850 and C9500 now support MPLS? There is a new 16
port 10G version of the C9500. I haven't looked into Nexus switches. Does
Nexus support full MPLS?


UADP based platforms, both older (C3650/3850) and newer (C9xxx) do
support MPLS encap and VXLAN encap and can be extended in future to
support others. There are new 9xxx based off UADP 3.0 with 40G and 100G
ports:

Nexus 7k supports MPLS with LDP while Nexus 9k supports MPLS but
with SR (IGP) or BGP-LU (no LDP support).
