I am running FRR 7.3 for RHEL 8 and implementing a key chain as follows:

key chain ospf-1

   key 1

      key-string <MyPassword>

     cryptographic-algorithm hmac-sha-384

When I issue the ‘cryptographic-algorithm hmac-sha-384’ command, I get an error ‘Validation’.

If I use 256, it accepts the command but both 384 and 512 fail.

How can I fix this?

Thanks
