Router Configuration Process Overview
Figure 10 displays the process to configure basic router parameters.
• Interface — A logical IP routing interface. Once created, attributes like an IP address, port,
link aggregation group or the system can be associated with the IP interface.
• Address — The address associates the device’s system name with the IP system address.
An IP address must be assigned to each IP interface.
• System interface — This command creates an association between the logical IP interface
and the system (loopback) address. The system interface address is the circuitless address
(loopback) and is used by default as the router ID for protocols such as OSPF and BGP.
• Router ID — (Optional) The router ID specifies the router's IP address.
• Autonomous system — (Optional) An autonomous system (AS) is a collection of
networks that are subdivided into smaller, more manageable areas.
• Confederation — (Optional) Creates confederation autonomous systems within an AS to
reduce the number of IBGP sessions required within an AS.
