The formula is n(n-1)/2 where n is the number of routers. 10 routers
would need 45 peerings. That's why we use route reflectors or
confederations :)

Is there a formula for the number of links needed for a full mesh?

EX: How many connections will be needed for 10 routers to accomplish

a full-mesh topology?
