The current dhcpv6 agent implementation cannot delegate agent operations to the pppoe interface prefix, such as the following directives:
listen-interface br1.2 {
address FF02::1:2
}
max-hop-count 10
upstream-interface pppoe0 {
address FF02::1:2
}
use-interface-id-optionThe expected behavior of the configuration is that the subordinate devices of br1.2 are expected to delegate requests to pppoe via the dhcpv6 prefix in order to complete the prefix delegate, but the actual situation is:
vyos@vyos# sudo /usr/sbin/dhcrelay -6 -pf /run/dhcp-relay/dhcrelay6.pid -l FF02::1:2%br1.2 -u FF02::1:2%pppoe0 -c 10 -I Internet Systems Consortium DHCP Relay Agent 4.4.1 Copyright 2004-2018 Internet Systems Consortium.

Is it possible to consider using Kea DHCPv6 instead of ISC DHCPv6, or a better solution?
