IXP - BGP Peering
S
Sandro Balestrino
Would you kindly consider preparing an explainer on how ISPs exchange routing information in an IXP.  I understand that there are two basic approaches to this - 1) full mesh direct peering , 2) routing server with one peering per ISP-2-SERVER. 
How are IP addresses allocated in an IXP. Do they use VLANS-802.1Q? How is the "switch" created - LISP-VXLAN? 
Who are the major IXPs - Equinex? 
These are the sorts of questions that should be addressed.
