  @mma678 You need to enable pre-fix delegation

Then in the VLAN under iPv6 get iPv6 pre-fix from pre-fix delegation.

To configure iPv6 go to the internet settibgs - the wan interface you want to configure iPv6 for and here enable pre-fix delegation.

Not sure how it is in Canada in Germany with the Deutsche Telekom you can use same PPPoE session than on iPv4 otherwise you need to reenter the same login information as for iPv4 or different ones for iPv6.

 

I know the description is a bit worse but I don't have time right now to look it up on pc so I tried my best.. ^^

Here is my configuration.

Enable IPv6 under Network Config/Network Settings/Internet.

Connection Type: Dynamic IP (SLAAC/DHCPv6)

Get IPv6 Address: Automatic

Prefix Delegation: Enable

Prefix Delegation Size: 56

DNS Address: Get from ISP Dynamically

Under Network Config/Network Settings/LAN/Configure IPv6

IPv6 Interface Type: SLAAC+Stateless DHCP

Prefix: Get from Prefix Delegation

IPv6 Prefix Delegation Interface: WAN

IPv6 Prefix ID: 0 (0-0) - this is the most confusing part. I would expect multiple Prefix ID to pick up; however, there is no option than 0 under other vlan IPv6 Prefix ID.

Address Prefix: xxxx:xxxx:xxxx:xxxx::/64

I am wondering if Omada routers can obtain multiple Prefix IDs when ISP Prefix Delegation Size is larger than 64.

Thank you!

Interesting, because in Germany we get a /48 iPv6 there I can obtain multiple prefix and set multiple prefix IDs 

But thinking of it 

128bit 

16bit-16bit-16bit-16bit-16bit-16bit-16bit-16bit

 

48bit is

XXXX:XXXX:XXXX/48
 

64bit is 
XXXX:XXXX:XXXX:XXXX/64

 

The last 64bit are by design for the device "interface identifier"

 

56bit would be

XXXX:XXXX:XXXX:XX/56

 

I know you can say
XXXX:XXXX:XXXX:XX-YY YY=8bit -->256 subnets

Speaking of I tried it out at myself, 10 minutes after I reconfigured the iPv6 prefix delegation to /56 I'm able to do prefix delegation with an ID from 0-255

So maybe just a wait a little bit.. 

 

 

I can see Delegated Prefix (IPv6) of xxxx:xxxx:xxxx:xx::/56 in my ISP's modem; however, I am uncertain if Omada router TL-ER7206 can actually obtain the correct PD size from my ISP. Is the issue from my router or ISP? I read from different source that Rogers Cable may provide PD size 64 to residential IPv6 connections.

Thank you!!     @Julian2111

It looks like my ISP only provides one delegated prefix ID to residential customers unfortunately.
