  29. .SH DESCRIPTION
  30. The \fBip sr\fR command is used to configure IPv6 Segment Routing (SRv6)
  31. internal parameters.
  32. .PP
  33. Those parameters include the mapping between an HMAC key ID and its associated
  34. hashing algorithm and secret, and the IPv6 address to use as source for encapsulated
  35. packets.
  36. .PP
  37. The \fBip sr hmac set\fR command prompts for a passphrase that will be used as the
  38. HMAC secret for the corresponding key ID. A blank passphrase removes the mapping.
  39. The currently supported algorithms for \fIALGO\fR are \fBsha1\fR and \fBsha256\fR.
  40. .PP
  41. If the tunnel source is set to the address :: (which is the default), then an address
  42. of the egress interface will be selected. As this operation may hinder performances,
  43. it is recommended to set a non-default address.
  45. .SH EXAMPLES
  46. .PP
  47. .SS Configure an HMAC mapping for key ID 42 and hashing algorithm SHA-256
  48. .nf
  49. # ip sr hmac set 42 sha256
  50. .PP
  51. .SS Set the tunnel source address to 2001:db8::1
  52. .nf
  53. # ip sr tunsrc set 2001:db8::1
