[Kea-users] DHCPv6 Relay listens on multicast and link-local only

Just experimenting with IPv6 and DHCP.

Suppose a routed environment where DHCPv6 and served are separated by 
few more routers.

I setup a dhcp-relay agent on end router as:

ipv6 dhcp relay destination 2001:DB8:0:1::16:2

This is the address of KEA server. I start it as usual, specifying "*" 
interface, but:

# ss -nl6u | grep 547
UNCONN     0      0      ff02::1:2%lan0.16:547 :::*
UNCONN     0      0 
fe80::20c:29ff:feb4:98c2%lan0.16:547                     :::*

That repeats for all other interfaces this host have, but all of them 
are multicast or link-local

Is there some option i should turn on?

kea version is 1.1.0
