DESCRIPTION

22       The ip sr command is used to configure IPv6 Segment Routing (SRv6)
23       internal parameters.
24
25       Those parameters include the mapping between an HMAC key ID and its
26       associated hashing algorithm and secret, and the IPv6 address to use as
27       source for encapsulated packets.
28
29       The ip sr hmac set command prompts for a passphrase that will be used
30       as the HMAC secret for the corresponding key ID. A blank passphrase
31       removes the mapping.  The currently supported algorithms for ALGO are
32       sha1 and sha256.
33
34       If the tunnel source is set to the address :: (which is the default),
35       then an address of the egress interface will be selected. As this oper‐
36       ation may hinder performances, it is recommended to set a non-default
37       address.

EXAMPLES

41   Configure an HMAC mapping for key ID 42 and hashing algorithm SHA-256
42       # ip sr hmac set 42 sha256
43
44   Set the tunnel source address to 2001:db8::1
45       # ip sr tunsrc set 2001:db8::1
