Keychains / Key Rotation / hmac-sha keys - OSPF Authentication - Practical OSPF

How can two routers change the authentication keys they are using without risking a neighbor adjacency going down? That is handled by Key Rotation. How can we configure more secure hashing algorithms for OSPF authentication like hmac-sha? That is handled by Key Chains. Both Keychains and Key Rotation are covered in this lesson. This is lesson 21 of the Practical OSPF series.
