Hi Nishal, 

Sorry, I just saw the list of the members here: http://www.mixp.org/#members.

Given the members list below, MIXP can not be classified in this case. 

PS: That’s what I will do for Seychelles-IX.

Because I did not spotted the website and hence the list :( that’s why I put “if”. Sorry

We are not in this case neither.  But still if we had 3 peers at the exchange point, they should peer with one another. Each of them should have 2 peers. 
A network that want to peer with only one AS is used to establish a private peering link. 

>> - If more than 3 peers are listed to me, then this only traceroute is not sufficient to decide; since an ISP can decide to peer with some members and not with others.

MIXP can be classified in this case thanks to its 10 peers. As I say, the traceroute only allows me to deduce that Mauritius Telecom and EMTEL are not peering at MIXP. 
But I can not say that MIXP is not working: this requires that I launch traceroutes among all members. 

> there are definitely *not* 30 ASNs in operation in mauritius.  you’re probably counting all afrinic’s ASNs - including the ones they use for anycast, that are not, ttbomk, even used in mauritius.  and networks that were made allocations but don’t use them.

Sure, I agree on this. Some ASes may not be in operation. We are in sync. 
 
Thanks for the infos so far. Thanks to Frank as well.
