Routing All hosts and gateways store routing tables Each row in the route table contains: – Destination address or address range – Next hop for that destination address range – The physical interface to use for that address range. (i.e.: which Ethernet card to use) Example: Destination Next Interface 129.186.4.0 129.186.5.254 en0 Routing In order to route a packet: 1. IP layer finds the route table entry where the destination address matches the range given in the table. 2. If the next hop falls within the local network, the packet is sent directly to the destination. Otherwise the packet is sent to the next hop.
