| /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. |
| |
| 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. |
