RFC 5709 on OSPF HMAC-SHA authentication revisited
Original: RFC 5709 defining HMAC-SHA cryptographic authentication for the OSPF protocol was published in October 2009 https:// cro
RFC 5709, published in October 2009, defines how OSPF routing protocol messages are authenticated using the HMAC-SHA cryptographic scheme. Networking commentary is revisiting the standard and explaining how cryptographic authentication works for OSPFv2, highlighting its role in securing routing infrastructure against spoofed route advertisements.
Why now: Renewed interest in routing protocol security has prompted discussion of the long-standing standard for OSPF authentication.
