Avaya P460 Configuration Guide 39 Chapter 5 Avaya P460 Layer 3 Features Introduction What is Routin g? Routing allows transfer of a data packet from sour ce to destination by a device called a router. Routing involves two basic acti vities: determination of optimal routing paths and transmissi on of inform ation packets through an internetwork.
Chapter 5 Avaya P460 Layer 3 Features 40 Avaya P460 Configuration Guide Figur e 5.1 Routing The routers obtain the relation between th e destination host’s protocol address and its physical address using the ARP request/reply mechanis m.The information is stored within the ARP table in the router.
Chapter 5 Avaya P460 Layer 3 Features Avaya P460 Configuration Guide 41 Routing Configuration Forwarding The P460 forwards IP packets be tween IP ne tworks. When it receives an IP pack et through one of its interfaces, it forwards the packet through one of its interfaces.
