ip-sr - IPv6 Segment Routing management
ip sr { COMMAND | help }
ip sr hmac show
ip sr hmac set KEYID ALGO
ip sr tunsrc show
ip sr tunsrc set ADDRESS
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.
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
