Model: T1600G-28PS(TL-SG2424P)  
Hardware Version: V3
Firmware Version: 3.0.5 Build 20200110 Rel.50207(s)

I'm trying to add a default IPv6 route to my switch, however it keeps failing on the IP address for some reason.

Any ideas as why this could be failing, please? Or how I should go about setting this up?

 

As IPv6 address I type :: to indicate this is the default gateway.

As prefix length I take 64 as honestly I don't know what value I should use.

In the next hop I enter the IPv6 address of my ISP router, which is in this format: 2a02:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx

 

However it keeps failing over and over. Even why I add the ::2 (for which I don't know the purpose neither).

Hi @Threesa

Thanks for posting in our business forum.
Prefix should be zero.

Hi @Threesa 

Thanks for posting in our business forum.

Your network diagram and setup. Next hop should be the accessible destination.

And please explain what you mean by fail. Not allow you to input the value? Or input successfully, but not working effectively.

What is the ISP v6 prefix?

If I input the entire local IPv6 address of my router (which should be the default Gateway) the frontend doesn't allow it.

If I remove the / the frontend accepts it, but then comes back with the message that it's an incorrect IP address.

 

IPv6 address (local) of the router: 2a02:1811:c511:f400::/64

Hi @Threesa 

Thanks for posting in our business forum.

Can you provide a diagram and full description of your front end, the issue and the error you are talking about?

What do you mean by removing the front and accepting it? Who reported incorrect IP? The front end??

I am still confused. With some screenshots to illustrate your issue. Please make a clear description.

IPv6 prefix 64 represents a subnet with a large number of available host IP addresses, while IPv6 prefix 0 denotes an unused or reserved IPV6 network address range.

That much is clear indeed. But why didn't my switch accept it as a value?

Does the 64 prefix imply a limited set of starting digits in the IP address (like the different scopes and subnets in IPv4)? So that the switch didn't accept it, because the IP I tried to enter was out of the range of a 64 prefix network?

Seem to be the case. Yes.
