From 0ee2f8285c81878687a9f92e6a3b0f10c4d75584 Mon Sep 17 00:00:00 2001 From: Christian Breunig Date: Wed, 20 Dec 2023 22:38:52 +0100 Subject: srv6: T591: enable SR enabled packet processing on defined interfaces The Linux Kernel needs to be told if IPv6 SR enabled packets whether should be processed or not. This is done using /proc/sys/net/conf//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 Or the VyOS CLI command: * set protocols segment-routing interface eth0 srv6 (cherry picked from commit 774cc97eda61eb0b91df820797fb3c705d0073d5) --- src/etc/sysctl.d/30-vyos-router.conf | 3 +++ 1 file changed, 3 insertions(+) (limited to 'src/etc') diff --git a/src/etc/sysctl.d/30-vyos-router.conf b/src/etc/sysctl.d/30-vyos-router.conf index 1c9b8999f..6291be5f0 100644 --- a/src/etc/sysctl.d/30-vyos-router.conf +++ b/src/etc/sysctl.d/30-vyos-router.conf @@ -105,3 +105,6 @@ net.core.rps_sock_flow_entries = 32768 net.core.default_qdisc=fq_codel net.ipv4.tcp_congestion_control=bbr +# Disable IPv6 Segment Routing packets by default +net.ipv6.conf.all.seg6_enabled = 0 +net.ipv6.conf.default.seg6_enabled = 0 -- cgit v1.2.3
