12.4.4 Configuring MD5 Authorization

Points to note

When configuring an authentication key, you must specify a key ID in addition to the key itself.

Command examples

1. (config)# router ospf 1

   (config-router)# area 1 authentication message-digest

   (config-router)# exit

   Configures area 1 to use MD5 authentication.

2. (config)# interface vlan 1

   (config-if)# ip ospf message-digest-key 1 md5 a1w@9a

   Sets a1w@9a as the authentication key associated with key ID 1. If VLAN 1 is assigned to area 1, OSPF packets conveyed over VLAN 1 are subject to authentication using message digests.
