IP-SR(8)                  (14 Apr 2017)                  IP-SR(8)

     NAME
          ip-sr - IPv6 Segment Routing management

     SYNOPSIS
          ip sr  { COMMAND | help }

          ip sr hmac show

          ip sr hmac set KEYID ALGO

          ip sr tunsrc show

          ip sr tunsrc set ADDRESS

     DESCRIPTION
          The ip sr 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 ip sr hmac set 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.

     EXAMPLES
        Configure an HMAC mapping for key
          # ip sr hmac set 42 sha256

        Set the tunnel source address to
          # ip sr tunsrc set 2001:db8::1
