IP-SR(8)                          Linux                         IP-SR(8)

NAME         top

       ip-sr - IPv6 Segment Routing management

SYNOPSIS         top

       ip sr  { COMMAND | help }

       ip sr hmac show

       ip sr hmac set KEYID ALGO

       ip sr tunsrc show

       ip sr tunsrc set ADDRESS

DESCRIPTION         top

       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         top

   Configure an HMAC mapping for key ID 42 and hashing algorithm SHA-256
       # ip sr hmac set 42 sha256

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