Hi,
I’m running 1.4 rolling and I’m curious about the DHCPv6 behaviour.
My system is getting a /128 IP address from upstream, working well so far.
Yet, when I ask vyos to renew by running renew dhcpv6 interface eth0 it will then release the IP address but will not get a new one. Only when I restart the system it then gets back an IPv6 from DHCPv6. The autoconf address of course is not affected by this.
I’m not sure if I’m reading the log correctly but to me it looks like my vyos device isn’t getting any response to the solicitation message, right?
