Routing principles 2002-03-11Östen Frånberg,6 Routing is a mechanism that builds a model of the network topology and its attributes. How networks are connected and the capacity (cost) to reach other networks. IGP Interior Gateway Protocol are used inside a network (ospf, Eigrp, rip, mfl,,) and EGP Exterior Gateway Protocol, between networks -BGP (or rather between routing domains - AS (Autonomy systems)) A B 10 40 10 20 ospf A B 10 40 10 20 ospf A B 10 40 10 20 ospf AS1066 AS4711 BGP AS2002 Ospf Open Shortest Path First, BGP Border Gateway Protocol,
