Hi Acee, What I meant is that BFD always augments the control palne protocols in ietf-routing model. And the BFD augmentation can be used as-is or mounted in LNE or in NI. Regards, Reshad. On 2018-02-17, 7:46 PM, "Acee Lindem (acee)" wrote: Hi Reshad, Are you

Hi Reshad, Are you saying that BFD would never augment the list of control place protocols in ietf-routing and always be at the root of the tree (whether it be the device, LNE, or NI)? I guess it doesn't have to be in the list since it will never install routes in the routing table. Thanks,

Re: [yang-doctors] Yangdoctors last call review of draft-ietf-bfd-yang-09

Ietf-bfd augments the ietf-routing model, that's not conditional. How the ietf-bfd model is used may vary: 1) It may be used "directly" in a device (i.e no schema mount) 2) It may be schema mounted for use in an LNE 3) It may be schema mounted for use in a VRF I thought this was the case for all

Re: [yang-doctors] Yangdoctors last call review of draft-ietf-bfd-yang-09

I thought about that after I replied. I guess you are saying that it is conceivable for a network device to support ietf-bfd but not support routing (ietf-routing)? Thanks, Acee On 2/17/18, 1:24 PM, "Reshad Rahman (rrahman)" wrote: Right, schema-mount can be used in

Right, schema-mount can be used in some cases (logical device or in a VRF) but doesn’t have to be used in other cases (e.g. network device which doesn't support VRFs). We will clarify the text, at a certain time we incorrectly thought that schema mount had to be used in all cases. Regards,
