The first step is to configure an interface used for Layer-3 IP. These can be physical interfaces, port-channels or virtual-interfaces (ve's). Virtual interfaces require thecreation of the underlying VLAN interface beforehand. Once the interface is selected, in order to configure Layer-3, users must go into the corresponding interface mode:
(conf-if-te-12/0/14)# ip address 188.8.131.52/24
Next, performno shutonthe interface(s). For more detailed and advanced information on configuring Layer-3 routing, consult the NOS Admin Guide Chapters 30 to 35.
