In a Nokia router, an interface is a logical named entity. An interface is created by specifying an interface name under the config>router context. This is the global router configuration context where objects like static routes are defined. An IP interface name can be up to 32 alphanumeric characters, must start with a letter, and is case-sensitive; for example, the interface name ‟1.1.1.1” is not allowed, but ‟int-1.1.1.1” is allowed.
To create an interface, the following basic configuration tasks must be performed.
Assign a name to the interface.
Associate an IP address with the interface.
Associate the interface with a network interface or the system interface.
Configure appropriate routing protocols.
A system interface and network interface must be configured.
