Description

I configured one of my LAB routers to make use of DHCPv6

vyos@vyos# show interfaces
 ethernet eth0 {
     duplex auto
     hw-id 00:50:56:00:00:fa
     smp-affinity auto
     speed auto
     vif 202 {
         address dhcp
         address dhcpv6
     }
 }

An IPv6 address is assigend as shown by:

vyos@vyos:~$ show interfaces ethernet
Codes: S - State, L - Link, u - Up, D - Down, A - Admin Down

But the show dhcpv6 client leases command fails

vyos@vyos:~$ show dhcpv6 client leases
There are no DHCPv6 leases.
vyos@vyos:~$ ls -la /var/lib/dhcp/dhclient_v6_*

Curiously, I can't reproduce it in the latest rolling, even though the code hasn't changed. We need to test in latest crux builds.
