       The ipsr command is used to configure IPv6 Segment Routing (SRv6) internal parameters.

       Those parameters include the mapping between an HMAC key ID and its associated hashing algorithm and
       secret, and the IPv6 address to use as source for encapsulated packets.

       The ipsrhmacset command prompts for a passphrase that will be used as the HMAC secret for the
       corresponding key ID. A blank passphrase removes the mapping.  The currently supported algorithms for
       ALGO are sha1 and sha256.

       If the tunnel source is set to the address :: (which is the default), then an address of the egress
       interface will be selected. As this operation may hinder performances, it is recommended to set a non-
       default address.
