Briefly describe OSPF authentication.
What will be an ideal response?
Routing update authentication is a basic security requirement for all modern routing protocols. OSPF provides authentication of routing table updates via several methods. OSPF supports using no authentication (the default), authentication with passwords sent in clear text, or authentication using MD5 hashing of a shared secret key. Since authentication using clear text results in almost no advantage over no authentication at all, it will not be discussed in this text. Instead, the following discussion focuses on MD5 authentication.
To perform MD5 authentication of routing updates in OSPF, two steps must be completed:
• Configuration of authentication keys on each OSPF interface
• Configuration of area authentication
