Configuring Keychain Authentication on an OSPFv2 Virtual Link

To configure keychain authentication 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 keychain command, with the required keychain name. The following example enables keychain authentication with the keychain name "mykeychain". 
    device(config-ospf-router)# area 1 virtual-link 20.1.1.1 authentication keychain mykeychain

The following example enables keychain authentication using the keychain name "mykeychain" 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 keychain mykeychain
