Cisco Public 2 General Role of the Router Functions of a Router Best Path Selections Forwarding packets to destination Routers perform packet forwarding by learning about remote networks and maintaining routing information. - The routers primary forwarding decision is based on Layer 3 information the destination IP address. - The router s routing table is used to find the best match between the destination IP of a packet and a network address in the routing table. - The routing table will ultimately determine the exit interface to forward the packet and the router will encapsulate that packet in the appropriated data link frame for that outgoing interface.
