, H1. Routing Concepts
1.1 Router Initial Configuration
Router functions
The router is responsible for the routing of traffic between networks
▪ Routers use static routes and dynamic routing protocols to learn about remote networks and build
their routing tables.
▪ Routers use routing tables to determine the best path to send packets.
▪ Routers encapsulate the packet and forward it to the interface indicated in routing table
Connect devices
To enable network access devices, must be configured with the following IP address information:
▪ IP address - Identifies a unique host on a local network.
▪ Subnet mask - Identifies the host’s network subnet.
▪ Default gateway - Identifies the router a packet is sent to when the destination is not on the same
local network subnet.
Statically Assigned IP address – The host is manually assigned an IP address, subnet mask and
default gateway. A DNS server IP address can also be assigned.
• Used to identify specific network resources such as network servers and printers.
• Can be used in very small networks with few hosts.
Dynamically Assigned IP Address – IP Address information is dynamically assigned by a server using
Dynamic Host Configuration Protocol (DHCP).
