3.1 Authentication and Verification of OSPF Routing Protocols - authentication message-digest
Information
To improve network security, the OSPF routing algorithm should support MD5 encryption authentication
Solution
Enable MD5 authentication ZXR10 (config-ospf-100-area-1)#authentication message-digest ZXR10 (config-ospf-100-if-fei-0/1/0/8.1)#authentication message-digest ZXR10 (config-ospf-100-if-fei-0/1/0/8.1)#message-digest-key 1 md5 fffff Note: Check has not been carried out since OSPF has not been configured.
