[Kea-users] DHCPv6 Relay Detection Help

[Robert Navarro]

Hello,

I've been trying to get the kea dhcpv6 server working with a brocade ICX
relay.

I read the information here:

https://kea.readthedocs.io/en/latest/arm/dhcp6-srv.html#dhcpv6-relays

and I saw these two dumps from the server, but I haven't been able to get
the correct `interface-id` to set in my configuration.

I've tried using the string printed in the debug output ("00:06:39:01"), no
luck

Could someone help?

VLAN 5
