Reference Guide

• All OSPFv3 routers in the area must share the same authentication key to exchange information. Only a non-
encrypted key is supported. For MD5 authentication, the non-encrypted key must be 32 plain hex digits. For
SHA-1 authentication, the non-encrypted key must be 40 hex digits. An encrypted key is not supported.
Example
OS10(config-router-ospfv3-100)# area 1 encryption ipsec spi 401 esp des
