Configuring the Hello Interval for Peer Interfaces

Hello packets are used to indicate to neighboring routers that the peer interface is still up and running. The hello interval must be the same for all routers on a shared logical IP network. You can specify a hello interval from 1 through 255 seconds. The default hello interval is normally 10 seconds. For nonbroadcast networks, the default hello interval is 120 seconds.

To specify how often the router sends hello packets out the peer interface, configure the hello-interval statement:




hello-interval seconds;

You can configure this statement at the following hierarchy levels:

[edit logical-systems logical-system-name protocols ospf area area-number peer-interface peer-interface-name]
[edit protocols ospf area area-number peer-interface peer-interface-name]
