Configuring Authentication Key Activation Wait Time on an OSPFv2 Virtual Link

The key activation wait time configures the time before an authentication key change is activated for an OSPFv2 virtual link. This allows you to coordinate a key change across devices to ensure there is no disruption to service.

To configure the authentication key activation wait time on an OSPFv2 virtual link, complete the following steps.

  1. Enter the configure terminal command to access global configuration mode. 
    device# configure terminal
  2. Enter the ip router-id command to specify the required router. 
    device(config)# ip router-id 10.1.1.1
  3. Enter the router ospf command to enter OSPFv2 configuration mode and enable OSPFv2 on the device. 
    device(config)# router ospf
  4. Enter the area area-ID virtual-link virtual-link-address authentication command, with the required wait time value. The wait time can be set from 0 through 14400 seconds. The following example configures a wait time of 600 seconds. 
    device(config-ospf-router)# area 1 virtual-link 20.1.1.1 authentication key-activation-wait-time 600

The following example enables an authentication key activation wait time of 600 seconds on the specified virtual link. 

device# configure terminal
device(config)# ip router-id 10.1.1.1
device(config)# router ospf
device(config-ospf-router)# area 1 virtual-link 20.1.1.1 authentication key-activation-wait-time 600
