/proc/sys/net/conf/<iface>/seg6_* variables:
|
|
============================================
|
|
|
|
seg6_enabled - BOOL
|
|
Accept or drop SR-enabled IPv6 packets on this interface.
|
|
|
|
Relevant packets are those with SRH present and DA = local.
|
|
|
|
* 0 - disabled (default)
|
|
* not 0 - enabled
|
|
|
|
seg6_require_hmac - INTEGER
|
|
Define HMAC policy for ingress SR-enabled packets on this interface.
|
|
|
|
* -1 - Ignore HMAC field
|
|
* 0 - Accept SR packets without HMAC, validate SR packets with HMAC
|
|
* 1 - Drop SR packets without HMAC, validate SR packets with HMAC
|
|
|
|
Default is 0.

/proc/sys/net/ipv6/seg6_* variables:
|
|
====================================
|
|
|
|
seg6_flowlabel - INTEGER
|
|
Controls the behaviour of computing the flowlabel of outer
|
|
IPv6 header in case of SR T.encaps
|
|
|
|
== =======================================================
|
|
-1 set flowlabel to zero.
|
|
0 copy flowlabel from Inner packet in case of Inner IPv6
|
|
(Set flowlabel to 0 in case IPv4/L2)
|
|
1 Compute the flowlabel using seg6_make_flowlabel()
|
|

|
Default is 0.
