Re: [c-nsp] PE "Sprawl" - P/Core Router suggestions.

Hi Phil - We currently run MPLS/OSPF/BGP...predominantly selling L3VPN services (And also vanilla Inet) - No intention of running user services on the new core, all will be on the PE's...The 5501 does look very nice...havent seen pricing on them yet...ball park "double" the price of the 5001?

Re: [c-nsp] PE "Sprawl" - P/Core Router suggestions.

Cheers Ted - Yes, looked at the 903's/RSP3 - I do like them..but they dont support segment routing (OSPF) Only ISIS currently?... and segment routing is something that I want to look at implementing. From: Ted Johansson Sent:

Thanks Saku (Apologies for top posting...hotmail/outlook live doesnt play nice with inline responses) So, the NCS5001 or 5501 look to be a nice fit (And migrating to BGP-free core) - As they are a very new box (the 5501/2 was only released few months or so ago?), Im a little wary of

Re: [c-nsp] PE "Sprawl" - P/Core Router suggestions.

Afaik, all the Cisco Jericho/Qumram based cards/fixed boxes use the 16MB on-chip and 4GB of external DRAM. The 4GB is broken up into 1000 byte chunks from what I remember. Phil -Original Message- From: cisco-nsp on behalf of Saku Ytti

That is the last spec I saw. Off-chip buffer on both base and SE. Off chip TCAM only on SE. On Thu, Dec 29, 2016 at 10:55 AM Saku Ytti wrote: > > Only the -SE SKU, NCS-5501 lacks external TCAM. > > Hmm, or did both of them have deep buffers and TCAM being only > addition on the

Re: [c-nsp] PE "Sprawl" - P/Core Router suggestions.

I have not used the 5501 but I've been told to be mindful of the buffers on it, specifically when shifting from higher to lower bps ports. That's SOP for switches, less usual for devices sold as routers though (the ME3600 & ASR920 come to mind). -- Stephen On 2016-12-29 9:19 AM, Phil

Re: [c-nsp] PE "Sprawl" - P/Core Router suggestions.

What kind of protocols are you running on the network? What’s the likelihood of running some user services or more advanced features on the new “core” boxes? Cisco gear the NCS 5501 would probably be my choice, it’s substantially less expensive than the 5502 if you don’t need the 100G
