<div class="moz-cite-prefix">Hello Nick, all,<br>
<br>
We, at GR-IX, are currently using a custom peering matrix tool,
created ages ago. Our peering tools is based on purely on sflow
data. The association between sflow and customers is done through
a MAC address database. A separate peering matrix is created for
v4 and v6. <br>
<br>
<a moz-do-not-send="true"
href="https://www.gr-ix.gr/peering-matrix/"
class="moz-txt-link-freetext">https://www.gr-ix.gr/peering-matrix/</a><br>
<br>
We are now considering redesign it from scratch. The most
important limitations of this approach is that, due to our
infrequent sampling, some "peerings" may get missed, esp between
large and small customers. Also, as the number of customers
increases, the full matrix is hard to read; a different UI is
necessary.<br>
<br>
Quite a while ago we evaluated the ixpmanager peering matrix. If I
remember correct, we spotted the following two limitations<br>
- it was using sflow to spot peering in control plane (bgp
sessions), rather than monitoring the data plane. On switches with
high sampling rate, such sessions would be easier to miss.<br>
- It was assuming that all members on the route servers peer with
each other.<br>
<br>
In our new peering matrix tool, we consider the following
enhancements<br>
(a) data-plane sflow will be used to identify baseline peerings<br>
(b) route servers will be used to identify additional peerings,
missed by sflow, but it will need to verify that the peers
actually exchange (advertise/accept) prefixes<br>
(c) Inspired by the RIPE country jedi tool
(<a moz-do-not-send="true"

class="moz-txt-link-freetext">http://sg-pub.ripe.net/emile/ixp-country-jedi/latest/GR/ixplans/index.html</a>),
we would like to explore using ripe atlas to augment the peering
matrix; eg find missing peerings, find private peerings, explore
routing of a specific AS behind a member etc.<br>
(d) augment the UI to be able to visualize such data<br>
<br>
Coming to IXPmanager, I wonder if you have any new features on
store for the peering matrix. If yes, can you please elaborate?<br>
<br>
In any case, we would be happy to co-operate and contribute back.<br>
<br>
Regards,<br>
<br>

peering matrix, but support for it is very messy because it wasn't
cleaned up properly in ixp manager v4 and has a bunch of ancient
dependencies going back to pre-release days. <br><br>This means that if
you set it up now, it's going to break by the time that 5.0 is
released. Can you wait for a while until we've reimplemented the code
and documented it properly?<br><br>Nick<br><br></div><div>_______________________________________________<br>INEX

<p>Hello, <br>
</p>
<p><br>
</p>
<p>I'm from CATNIX (Internet exchange of Catalonia). I'm interested
in create a Peering Matrix, so I installed the IXP Manager. Once
is installed as I can see in this page <a moz-do-not-send="true"
href="http://docs.ixpmanager.org/" class="moz-txt-link-freetext">http://docs.ixpmanager.org/</a>
the feature "Peering Matrix" doesn't appear. Is this feature
available yet?. In this case I would like more information about
the steps to create a peering Matrix. <br>
</p>
<p><br>
</p>
<p>On the other hand, cheking the configuration I see that it's
necessary to introduce a vlan but in my case I send the fluxes by
a management vlan different from de DMZ of CATNIX. When i check in
dashboard doesn't recognized the ip of the interface of the server
that I installed the IXP Manager.</p>
<p><br>
</p>
<p><br>
</p>
<p><br>
</p>
<p># For some actions (e.g. peering matrix) we need to know what
VLAN to show by default.<br>
# This is the vlan.id database entry (i.e. not the VLAN
number/tag!)<br>
IDENTITY_DEFAULT_VLAN=1</p>
<p><br>
</p>
<p><br>
</p>
<p>If someone have more information of the steps for doing a peering
matrix I would be very grateful. :)</p>
<p><br>
</p>
<br>
<p><br>
</p>
<p><br>
</p>
Thank you very much,
