Configuring keychain authentication on an OSPFv3 virtual link

To configure keychain authentication on an OSPFv3 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 ipv6 router ospf command to enter OSPFv3 configuration mode and enable OSPFv3 on the device. 
    device(config)# ipv6 router ospf
  4. Enter area area-ID virtual-link virtual-link-address authentication command, with the required keychain. The following example enables keychain authentication with the keychain "mykeychain". 
    device(config-ospf6-router)# area 1 virtual-link 20.1.1.1 authentication keychain mykeychain

The following example enables keychain authentication using the keychain "mykeychain" on the specified virtual link. 

device# configure terminal
device(config)# ip router-id 10.1.1.1
device(config)# ipv6 router ospf
device(config-ospf6-router)# area 1 virtual-link 20.1.1.1 authentication keychain mykeychain
