Setting OSPF Adjacency with Cisco Routers

To establish an OSPF adjacency between Dell Networking and Cisco routers, the hello interval and dead interval must be the same on both routers.

In Dell Networking OS, the OSPF dead interval value is, by default, set to 40 seconds, and is independent of the OSPF hello interval. Configuring a hello interval does not change the dead interval in Dell. In contrast, the OSPF dead interval on a Cisco router is, by default, four times as long as the hello interval. Changing the hello interval on the Cisco router automatically changes the dead interval.

For more information regarding this functionality or for assistance, go to http://www.dell.com/support/my-support/.

To ensure equal intervals between the routers, use the following command.

Manually set the dead interval of the Dell Networking router to match the Cisco configuration. INTERFACE mode ip ospf dead-interval <x>

Example of Setting a Dead Interval

In the following example, the dead interval is set at 4x the hello interval (shown in bold). 

Dell(conf)#int tengig 2/2
                                 Dell(conf-if-te-2/2)#ip ospf hello-interval 20
                                 Dell
                                 (conf-if-te-2/2)#ip ospf dead-interval 80
                                 
                                 Dell(conf-if-te-2/2)#

In the following example, the dead interval is set at 4x the hello interval (shown in bold). 

Dell (conf-if-te-2/2)#ip ospf dead-interval 20
                                 Dell (conf-if-te-2/2)#do show ip os int tengig 1/3
