Dear Community,<br>
How is the peering policy implemented in the IXP<br>
manager at the backend? Is it done by route server? If the route server is<br>
not used then will the selective peering still can occur? If yes then how?<br>
<br>
Also, if the route server is handling all the peering policies such as open<br>
or selective then how is it handling? Explaining the question through an<br>
example. Suppose there are two ISPs: ISP A and ISP B. Can an ISP A provide<br>
the prefixes in selective peering through its customer portal that I want<br>
these prefixes to go to ISP B and vice versa. If yes, then how is this<br>
thing implemented? Is it implemented through route server or what? If it is<br>
implemented through route server then how? Can you share any link for such<br>
configurations?<br>
<br>
So, the basic question is:<br>
How is selective peering being handled at the backend?<br>
<br>
-----------<br>
One more question is that is there any specific application we should use<br>
for route server? I am using quagga for route server.<br>
<br>
Thanks for always helping the deployment of IXP manager in Pakistan<br>
Sincerely,<br>
Haider<br>

<br>
It isn't. The participants at the IXP determine how they want their <br>
prefixes to be exchanged.<br>
<br>
If they have bilateral BGP sessions, then this is entirely a matter for <br>
them, and the IXP has no way of interfering with this. If they choose <br>
to use the route servers, then:<br>
<br>
outgoing prefixes: they can use the standard community tags if they want <br>
their prefixes to be sent or blocked for other RS clients.<br>
<br>
incoming prefixes: they can use standard BGP as path filters or prefix <br>
lists to filter out what they don't want to see.<br>
<br>
The IXP doesn't control any of this. The control is solely in the hands <br>
of the IXP participants because they are better at deciding what's most <br>
appropriate for their routing policy.<br>
