IP-SR(8)                             Linux                            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 oper-
       ation may hinder performances, it is recommended to set a non-default
       address.
EXAMPLES
   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
