Solved: IPv6 Track Interface Option?

[pmisch]

Hi there,

in pfSense you can configure a downstream interface to track an upstream interface (like WAN) and just give a Network Identifier (like 1000) so you get your automatic IP configuration without ever specifying one. Example: 2a14:a30a:af00:1000::1/64
The upstream Interface is requesting IP addresses via IPv6 Prefix Delegation, so there's a pool waiting to choose an IP from.
Is there such option in OpenWrt?

Thank you

• ip6assign : Prefix size used for assigned prefix to the interface (e.g. 64 will assign /64-prefixes)
• ip6hint : Subprefix ID to be used if available (e.g. 1234 with an ip6assign of 64 will assign prefixes of the form …:1234::/64)
• ip6class : Filter for prefix classes to accept on this interface (e.g. wan6 will only assign prefixes with class wan6 but not e.g. local)
