DHCP(ipv4) + DHCPv6-PD + IPv6 Autoconfig ONT from OLT as L3 Gateway

Hello team,

1. I am trying to configure OLT as gateway L3

Is this a good practice or is not recommended?

2. I have an IPv4 DHCP relay working for ONT address allocation.

3. I am stuck on automatic configuring IPv6 for ONT from OLT. I can see ONT from OLT as IPv6 neighbor as a local link, but address acquisition does not occur and ipv6 WAN status in OLT is "disconnected"

4 Does the OLT support the auto-config ipv6 setting for the wan address and the dhcpv6 relay for prefix delegation?

It is asking too much for a configuration example or a link to the documentation. I searched, I searched a lot, but with no luck.

service-port 2757 vlan 556 gpon 0/14/10 ont 1 gemport 1 multi-service user-vlan 97 tag-transform default inbound traffic-table index 14 outbound traffic-table index 15

interface vlanif556

 ip address 100.127.248.1 255.255.248.0

 dhcp-server 19

 ipv6 enable

 ipv6 address 2001:db8:0:3::1/64

 undo ipv6 nd ra halt

The current scenario, running in production.

It works just fine.

Desired work scenario.

Thanks in advance.
