Re: New Switches with Broadcom StrataDNX
It depends… there’s a phenomenon called “next-hop flattening” which has to do with lookup recursiveness within the silicon. Unless this is done (and this is big piece of work) not everything supported on Trio or Ezchip can be supported. In general – Jericho (and its followers) is a great piece of silicon made by clueful folks… watch this space closely Jeff From: Colton Conor Date: Monday, April 18, 2016 at 11:44 AM To: lincoln dale Cc: Jeff Tantsura , "nanog@nanog.org" Subject: Re: New Switches with Broadcom StrataDNX So can this compete routing wise against something like a Juniper MX104 or Cisco ASR 9001?

I don't think the FIB needs to have specific support for selective programming. I think that comes in the code to instruct the control plane what it should download to the FIB. Cisco's and Juniper's support of this is on FIB that has been in production long before the feature became available. It was just added to code. Mark.
Re: New Switches with Broadcom StrataDNX
Good point, there are many people looking at what I call FIB optimization right now. The key is having the programmability on the device to make it happen. Juniper/Cisco support it using policies to filter RIB->FIB and I believe both also do per-NPU/PFE localized FIBs now. I am not sure if that’s something supported on this new Broadcom chipset.

Re: New Switches with Broadcom StrataDNX
Hi, Some points: 1.DNX SDK is significantly different from SGX, adopted by Cumulus and such, yet to be done, and this is not negligible amount of work 2.if you are not interested in capacity but in scale, there’re other BCM chips, perhaps more suitable 3.you don’t have to have all the forwarding entries populated in silicon, as an example - take a look at http://sdn-internet-router-sir.readthedocs.org, code at https://github.com/dbarrosop/sir, one could also leverage approach we have taken in EVPN - decoupling RIB from FIB completely 4.NG silicon will do 1M+ LPM's Cheers, Jeff On 1/19/16, 06:29, "NANOG on behalf of Colton Conor" wrote: >I was hoping this new Broadcom chip would be able to support enough routes >to hold a full BGP table, and be used for something like cumulus linux.

Re: New Switches with Broadcom StrataDNX
It does support a path to use an external TCAM if vendors do that, and will support 1M+ entries. It will be more expensive and the datapath will be slower which will impact the performance a bit. I think you’ll see this make its way into something like a 48x10G/4x100G (or 40G) type platform but we’ll see.

Merchant chips have focused on bandwidth scaling at the expense of key features available in custom silicon. This has forced me to avoid certain hardware from even the big vendors. Bandwidth is not everything... if the approach with this new chip is different, I'd be interested. Time to hunt... Mark.
