12.4.3 Configuring Plaintext Password Authentication

Points to note

The example below shows how to use the area authentication command to set the authentication method for an OSPF area.

Command examples

1. (config)# router ospf 1

   (config-router)# area 1 authentication

   (config-router)# exit

   Configures area 1 to use plain-text password authentication.

2. (config)# interface vlan 1

   (config-if)# ip ospf authentication-key a1w@9a

   Sets a1w@9a as the authentication key.

   If VLAN 1 is assigned to area 1, OSPF packets conveyed over VLAN 1 are subject to plain-text password authentication.
