.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
