| .SH DESCRIPTION |
| The \fBip sr\fR command is used to configure IPv6 Segment Routing (SRv6) |
| internal parameters. |
| .PP |
| 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. |
| .PP |
| The \fBip sr hmac set\fR 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 \fIALGO\fR are \fBsha1\fR and \fBsha256\fR. |
| .PP |
| 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. |
| |
| .SH EXAMPLES |
| .PP |
| .SS Configure an HMAC mapping for key ID 42 and hashing algorithm SHA-256 |
| .nf |
| # ip sr hmac set 42 sha256 |
| .PP |
| .SS Set the tunnel source address to 2001:db8::1 |
| .nf |
| # ip sr tunsrc set 2001:db8::1 |
