Re: Comments on l2tpv3-yang-model: Covering keyed-v6-tunnel?

Hi Qi,

>> [Bing3] For auto tunnels, we defined the model according to RFC3931; 
>> for static tunnels, we followed the keyed-ipv6-tunnel. Does it make sense to you?

> [Qi] Yes. Then here comes another question: is the subtree "l2tpv3CtrlInstances" 
> used for both the "auto" mode and the "static" mode? I assume it to be "NO".

[Bing] You're right. The CtrlInstances only applies for "auto" mode. The ctrlName node under the auto tunnel list references the relevant CtrlInstance.
We'll make it clearer in the next version.

[Bing] Personally, I think it's a good idea. Let's hear others' opinions when update the next version. Thank you.

Best regards,
