答
OSPF supports 2 types of authentication:
Simple password (or plain text) authentication
MD5 authentication
Router generates and checks every OSPF packet.Router authenticates the source of each routing update packet that it receives.
Configure a “key” (password); each participating neighbor must have same key configured.
For reference
