+BGP configuration considerations:
+- subdivide single "public" AS (100) into multiple internal sub-AS (BGP confederation)
+	- spine layer: all switches reside in one AS (65000)
+	- leaf layer: every switch resides in its own AS (65001, 65002, 65003, 65004)
+- direct static peering between leaf and spine nodes (interfaces of interconnection network, no loopbacks)
+	- allow load balancing across multiple BGP paths with equal costs (=> ECMP)
+		- maximum path count equals number of used spine switches
+		- only one AS at spine layer => no BGP multipath relaxing necessary
+- every BGP router is used as next hop in its advertised/forwarded routing messages
