Information
Enable Open Shortest Path First (OSPF) Message Digest 5 (MD5) authentication.
Rationale:
This is part of the OSPF authentication setup
Solution
Configure the appropriate interface(s) for Message Digest authentication
hostname(config)#interface {interface_name}
hostname(config-if)#ip ospf message-digest-key {ospf_md5_key-id} md5 {ospf_md5_key}
Impact:
Organizations should plan and implement enterprise security policies that require rigorous authentication methods for routing protocols. Configuring the proper interface(s) for 'ip ospf message-digest-key md5' enforces these policies by restricting exchanges between network devices.
Default Value:
Not set
