I have two Routers:
I created a vlan interface at each router, with IPv6 only - the address is being auto assigned from the DHCP-PD of the WAN6 interface.
When I connect Fedora 34 clients to that vlan of routers one by one:
- w/ Router1, client can get IPv6 address
- w/ Router2, client cannnot got IPv6 address.
There are lots of new options in the DHCPv6 settings in 21.02.0.
How to make it working like a 19.07 DHCPv6?
