sysctl interface settings

This example configures sysctl interface settings:

  • enable ip forwarding for all interfaces
  • ignore ipv6 router advertisments by default
  • accept ipv6 router advertisments on eth0 and generate a private ipv6 address
  • configure a static ipv6 address on eth1

ifstate

options:
  sysctl:
    all:
      ipv6:
        forwarding: 1
interfaces:
- name: eth0
  link:
    kind: physical
    state: up
  sysctl:
    ipv6:
      accept_ra: 2
      addr_gen_mode: 3
- name: eth1
  addresses:
  - 2001:db8::defa/64
  link:
    kind: physical
    state: up

manually

sysctl net.ipv6.conf.all.forwarding=1
sysctl net.ipv6.conf.eth0.accept_ra=2
sysctl net.ipv6.conf.eth0.addr_gen_mode=3
ip address add 2001:db8::defa/64 dev eth1
ip set link dev eth0 up
