by doing nothing, the router keeps sending the messages, wasting some small bit of CPU cycles and effort. Alternately, the engineer can configure the interface as an OSPF passive interface, telling the router to do the following:
This chapter describes how to configure OSPF and several key features, including authentication, passive interfaces, default route injection, inter゛rea summarization, and route filtering. OSPF is a link﹕tate protocol, meaning that all routers in an autonomous system (AS) share the states of their...
A disabled interface is a passive interface, which cannot send any hello packet. To make no routing information obtained by other routers on a network segment, you can use this command to disable the interface from sending OSPF packets. Examples # Disable an interface from sending OSPF packets....
