Routing Loop
“maximum-paths” tells the router to reset the NEXT_HOP to himself
R3 sets NEXT_HOP to 3.3.3.3
Forces traffic to come to him so he can load-balance
Is typically used for multiple eBGP sessions to an AS
Be careful when using in Confederations!!
Need to make R2 prefer the path from R1 to prevent the routing loop
Make IGP metric to 1.1.1.1 better than IGP metric to 4.4.4.4
