[c-nsp] LSR platforms

[Phil Bedard]

Full disclosure I work for Cisco.

There are a ton of Broadcom based boxes deployed in all roles these days.  Certainly quite a few in P/LSR roles.

The 55A1-24H, 36H are 100G dense J+ based platforms.  There are 10G dense platforms based on the same chips (55A1-48Q).   There are also some newer J2 platforms that work really well as LSRs also if you are looking at a fixed platform.

8000 is a good fit if you want more capacity and a migration path to more 400G.   The main difference between the 10001-36MR and the 8201-FH (32x400G) is the 10001 uses several NPUs to reach 9.6TB, the 8201-FH (32x400G) uses a single 12.8Tbps NPU.    The power consumption of it is about 25% of the 10001.

Thanks,
Phil

I'm hesitant to recommend Broadcom based platform (NCS5k/Arista/ACX) for platform certification testing in a worry that it will bite us in a long run, though less so for a P role (as opposed to PE role).

What about Cisco 8201 vs Juniper PTX10001-36MR -these two seem to be identical, have the same speeds and feeds.
What I like about these is that they are 400G optimized to future proof the core.
