[IPV6ACCEPTRA] SECTION OPTIONS

The [IPv6AcceptRA] section configures the IPv6 Router Advertisement (RA) client, if it is enabled with the IPv6AcceptRA= setting described above:

UseDNS= When true (the default), the DNS servers received in the Router Advertisement will be used.

This corresponds to the nameserver option in resolv.conf(5).

UseDomains= Takes a boolean, or the special value "route". When true, the domain name received via IPv6 Router Advertisement (RA) will be used as DNS search domain over this link, similar to the effect of the Domains= setting. If set to "route", the domain name received via IPv6 RA will be used for routing DNS queries only, but not for searching, similar to the effect of the Domains= setting when the argument is prefixed with "~". Defaults to false.

It is recommended to enable this option only on trusted networks, as setting this affects resolution of all hostnames, in particular of single-label names. It is generally safer to use the supplied domain only as routing domain, rather than as search domain, in order to not have it affect local resolution of single-label names.

When set to true, this setting corresponds to the domain option in resolv.conf(5).

RouteTable=num The table identifier for the routes received in the Router Advertisement (a number between 1 and 4294967295, or 0 to unset). The table can be retrieved using ip route show table num.

RouteMetric= Set the routing metric for the routes received in the Router Advertisement. Takes an unsigned integer in the range 0...4294967295. Defaults to 1024.

UseMTU= Takes a boolean. When true, the MTU received in the Router Advertisement will be used. Defaults to true.

UseAutonomousPrefix= When true (the default), the autonomous prefix received in the Router Advertisement will be used and take precedence over any statically configured ones.

UseOnLinkPrefix= When true (the default), the onlink prefix received in the Router Advertisement will be used and takes precedence over any statically configured ones.

RouterDenyList= A whitespace-separated list of IPv6 router addresses. Each address can optionally take a prefix length after "/". Any information advertised by the listed router is ignored.

RouterAllowList= A whitespace-separated list of IPv6 router addresses. Each address can optionally take a prefix length after "/". Only information advertised by the listed router is accepted. Note that if RouterAllowList= is configured then RouterDenyList= is ignored.

PrefixDenyList= A whitespace-separated list of IPv6 prefixes. Each prefix can optionally take its prefix length after "/". IPv6 prefixes supplied via router advertisements in the list are ignored.

PrefixAllowList= A whitespace-separated list of IPv6 prefixes. Each prefix can optionally take its prefix length after "/". IPv6 prefixes supplied via router advertisements in the list are allowed. Note that if PrefixAllowList= is configured then PrefixDenyList= is ignored.

RouteDenyList= A whitespace-separated list of IPv6 route prefixes. Each prefix can optionally take its prefix length after "/". IPv6 route prefixes supplied via router advertisements in the list are ignored.

RouteAllowList= A whitespace-separated list of IPv6 route prefixes. Each prefix can optionally take its prefix length after "/". IPv6 route prefixes supplied via router advertisements in the list are allowed. Note that if RouteAllowList= is configured then RouteDenyList= is ignored.

DHCPv6Client= Takes a boolean, or the special value "always". When true or "always", the DHCPv6 client will be started when the RA has the managed or other information flag. If set to "always", the DHCPv6 client will also be started in managed mode when neither managed nor other information flag is set in the RA. Defaults to true.
