11 | seg6_enabled - BOOL | |
12 | Accept or drop SR-enabled IPv6 packets on this interface. | |
13 | ||
14 | Relevant packets are those with SRH present and DA = local. | |
15 | ||
16 | * 0 - disabled (default) | |
17 | * not 0 - enabled | |
18 | ||
19 | seg6_require_hmac - INTEGER | |
20 | Define HMAC policy for ingress SR-enabled packets on this interface. | |
21 | ||
22 | * -1 - Ignore HMAC field | |
23 | * 0 - Accept SR packets without HMAC, validate SR packets with HMAC | |
24 | * 1 - Drop SR packets without HMAC, validate SR packets with HMAC | |

29 | Controls the behaviour of computing the flowlabel of outer | |
30 | IPv6 header in case of SR T.encaps | |

32 | == ======================================================= | |
33 | -1 set flowlabel to zero. | |
34 | 0 copy flowlabel from Inner packet in case of Inner IPv6 | |
35 | (Set flowlabel to 0 in case IPv4/L2) | |
