If the ip6hint is not suitable for the given ip6assign, it will be rounded down to the nearest possible value. Setting the ip6assign-parameter to a value < 64 will allow the DHCPv6-server to hand out all but the first /64 via DHCPv6-Prefix Delegation to downstream routers on the interface. If ip6hint is not set, an arbitrary ID will be chosen. If this fails as well, the prefix length is reduced until the assignment can be satisfied. In this case, the system will first try to assign a prefix with the same length but different subprefix-ID. Ip6assign and / or ip6hint-settings might be ignored if the desired subprefix cannot be assigned. wan6 will only assign prefixes with class “wan6” but not e.g. Ip6class: Filter for prefix classes to accept on this interface (e.g. Specifies the default route metric to useĭownstream configuration for LAN interfaces IPv6 prefix routed here for use on other interfaces (Barrier Breaker and later only)ĭefine the IPv6 prefix-classes this interface will accept Hint the subprefix-ID that should be delegated as hexadecimal number (see Downstream configuration below) The option was introduced by this commit to netifd in Jan 2015.Īssign given IPv6 default gateway to this interfaceĭelegate a prefix of given length to this interface (see Downstream configuration below) When IPv6 prefix (like 'a:b:c:d::') is received from a delegating server, use the suffix (like '::1') to form the IPv6 address ('a:b:c:d::1') for this interface. In addition, you also need to add its name to a suitable firewall zone in /etc/config/firewall.Īssign given IPv6 address to this interface (CIDR notation)Īllowed values: 'eui64', 'random', fixed value like '::1:2'. Note: To automatically configure ds-lite from dhcpv6, you need to create an interface with option auto 0 and put its name as the 'iface_dslite' parameter.
