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) in-
ternal parameters.
Those parameters include the mapping between an HMAC key ID and its as-
sociated 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 re-
moves 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
