cisco ccna uk.The routing table is an important component for routers to make packet forwarding decisions. How are the contents of this table populated? After the IP address is properly configured and the status of the interface (NIC) is UP, the router residence) adds the network connected to the interface as a directly connected route in the routing table. In effect, the router (host) determines the destination network for the directly connected route based on the IP address and subnet mask of the interface (NIC). The IP address of the host's default gateway can be either statically configured or dynamically obtained via DHCP, as mentioned in section 1.4.4./JH As for the rest of the routing table, it is divided into the following two categories.[Key Points Static routes: are routes that are manually added by network administrators. When the IP routing protocol is not enabled on the unit network or the network device cannot run the IP routing protocol, you have to configure static routes manually.. Dynamic routes: are routes that are dynamically learned by network devices through some IP routing protocol. The IP routing protocol (IProuting protocol) is a protocol for exchanging information between Layer 3 devices (for example, between routers and the camera), the purpose of the exchange of information is to create a routing table, allowing routers to follow the routing table "across the network"1.4 Internet Protocols and Layer 3 Technologies 65Routing IP packets. A routableprotocol is the actual protocol used to transmit information and forward packets.protocols. Both IPv4 and IPv6 are routable protocols.Each routing protocol has the following two main characteristics that need to be defined by itself. How information is exchanged, the type of exchange, and the timing of the exchange. What algorithms each device will use to calculate the best path to the destination network. This book will not delve into all the routing protocols in use, but it is important that the reader should at least be familiar with the IP routingprotocols and how they function.HipNote Routing protocols can be divided into two broad categories based on where they operate in the network. This is the classification routing protocols
