Hi Mathias

Thank you for you Feedback. It seems to be a good alternative to our currently installed VXR7206 with NPE-400.

Also, if I look on the performance Sheet from Cisco, where the 2921 even outperform the NPE-400 a little bit.

I think, we will take a deeper look in this solutions.

Thanks you again.

Kind Regards

Patrick

PS: Hope your installation work at EBM, which you have done about 2 weeks ago, went well ;-)

Hi Patrick

I've seen 2921 doing 150 Mbit/s mixed HTTP traffic (without many services configured and with about 50% CPU load). And yes, with the new IOS version 15 you can run full BGP and IPv6 BGP with the IP Base Feature Set. I can confirm this. Also OSPFv3 is working in IP Base.

Since this is a software router it depends very much what services you configure (rpf checks etc.). Also if you get DoSed the box won't last for long. But they're pretty powerful if you consider the price. You can get it with 1.5 or 1 GBytes factory upgraded memory, 512 MB should work too, but IMHO not for long :)

If you want to go a step higher consider a pair of ASR1001, but the price gap from the 2921 or even 2951 is fairly large.

Hi

@Manfredo/Daniele - Hmm..Already thought about perhaps switching to one of this routers. Is a 2921 really taking all (Full IPv4/IPv6 Features incl. all BGP, ASN 4-bytes) just with the regular IP Base = Part-No. CISCO2921/K9? What can we expect as maximum traffic for this configuration?

@Andy/Michael - Would the SP not be sufficient. Or why should we use Advanced IP or Advanced Enterprise service?

@Kurt - What are the hardware specification of your setup for you Quagga? Is Quagga able to do HSRP or something similar? How much bandwidth do you handle with that configuration?

@All, is enabling of IPv6 taking that much memory, so 512 MB with two full feed and some SwissIX peering would be enough?

Thanks already for your pervious answers.

Patrick,

only one issue on RAM needed. NPE400 supports 512Mb, that's not enough for a full-view BGP. We better use 7301 or 2921 with 1Gb and 15.0 software.

Cheers Manfredo

Has anybody here a 7206VXR + NPE400 running and doing IPv6 / Full BGP / 4-byte ASN? If yes, which IOS Version and Package do you have installed. How much memory / flash do you have installed?

We currently have "only" two upstreams and some SwissIX peering.

Hey Patrick. :-)

I was running some 7206 in my past job, although these had an NPE-G1 or NPE-G2, with 1GB of RAM.

You need Advanced IP Services or Advanced Enterprise services for v6 routing, and Multiprotocol (i.e. v4 and v6) BGP. You need 12.4(24)T, or 12.2(33)SRE1 (or later, including all 15.0) for 4 byte ASNs.

So you should get away with, assuming your NPE has the storage and RAM : c7200-advipservicesk9-mz.12.2-33.SRE1 to SRE4, or c7200-advipservicesk9-mz.124-24.T5.bin.

And of course, we at as6939/he.net would like to help with your v6. :-)

Hi Michael

Sorry, but I miss to mention one important thing, we have currently two 7206VXR/NPE-400. Each of them is connect to one Upstream of our two upstream. Each of the upstreams is sending a full BGP Feed. One router is also connected to the SwissIX for peering.

I hate the feature browser. I doesn't really help to find things. I.e. with the mentioned IOS, I don't find 4-byte AS Number in the feature set. I compared also your suggested version against our currently installed version and if you look at the result, I really cannot say, what we are missing today with our version we have installed. To say it in short, if you know exactly, which feature you are looking for (and you know, how Cisco has named it), then it will help, but if you want to make sure, that you have just all, what you need today to have full ipv6/bgp capabilities, it doesn't really help, because in my case, I don't know exactly, for which of the 30-40 bgp feature and 30-40 ipv6 feature have to look for (which name).

Thanks anyway to pointing to it.

The memory usage on both for the BGP Router Process is about 200-210 MB.

If I understand the EOL information correct, it's just the EOL of the Bundle 7206VXR/NPE-400, which is clear, because today, most people will buy the NPE-G1 or NPE-G2, which is mentioned there as recommended upgrade path.

Kind Regards

Patrick

Hy Patrick,

For a Service Provider or Carrier yes. The most importing stuff is in: (BGP/OSPF/HSRP/VRRP/ASN4BYTE/IPV6/ACL/NETFLOW)

check out the feature list: c7200-spservicesk9-mz.122-33.SRE3 -> http://tools.cisco.com/ITDIT/CFN/Dispatch

GET Memory usage BGP Process: show processes memory | begin BGP Router Get the holding row are in bytes

So if you try to use 2 ipv4 full peerings you router maybe reload cause of memory overflow. Or you optimize the routing tables maybe it holds, One ipv4 full table and one or two ipv6 full tables, that should work quite nicely.

But if you would make it professional you get a little newer system ;)

Hi Daniele

Thanks for your real work sample. As I already written to Mathias, I really think, you should take a deeper look on switching perhaps to two 2921 (side effect will be, that we will will a little bit of Rackspace ;-).

Kind Regards

Patrick

We have 4 x 2921 as frontend BGP routers carring 100 Mbps average with full BGP table @ v4 / v6. With 1 GB RAM and a lean straight configuration the CPU load is topping at 18%.

Regarding the memory for full-table BGP: With 512 M in total you will run really short (depending how much is reserved for I/O, buffers, ...). With 1G you still have plenty of space to be filled with v6 prefixes :-)
