IPv6

Run the VPN over IPv6 with static addresses. Experimental, single-stack only.

Experimental feature. IPv6 support is provisional and has known gaps — see below before relying on it.

IPv6 works with static addresses only. One address per interface; dual stack is not supported, so a node is either IPv4 or IPv6, not both.

$ EDGEVPNTOKEN=.. edgevpn --address fd:ed4e::11/64 --mtu 1500

Two things to get right:

The address must be static. --dhcp allocates IPv4 addresses only, so it cannot be combined with an IPv6 --address.
--mtu must be above 1280, the IPv6 minimum link MTU. EdgeVPN’s default is 1200, which is below it, so you have to set --mtu explicitly.

Tracking issue #15 is still open at the time of writing; it is the place to check for the current state of IPv6 support.
