Hi Haibo,
thank you for the clarification. I may suggest a text for Section 3:
In some EVPN deployments, for example, when it spans over multiple domains,
only one of a pair of interconnected PEs benefits from monitoring the
status of the connection. In such a case, using S-BFD [RFC7880] is
advant
Hi Greg,
Thanks for you comments.
Yes, the resources will save at PE1 and PE2 as figure 1. This is a typical 3PE
scenario.
The service is like this:
+-++-++-+
| UCE1|| APE1||SPE1 |,
+-++-+` /+-+ `.

Hi Haibo,
thank you for your expedient response. If I understand the scenario you're
addressing, it is where a single PE with moderate resources is connected to
a PE that acts as the edge device for the access network. To improve the
quality of user experience, customer's PE is connected to a secon
Hi Reshad,
Thanks for your comments first.
|Authors, in section 3.1 3rd paragraph, last sentence, I'm not sure I fully
understand. Instead of |having 2 S-BFD sessions on PE3 (as initiator) to PE1
and PE2 (the responders), how are you merging |this into 1 single session?

Hi Greg,
Thanks for your comments.
The scenario you pointed out is a 4PE scenario, but in our solution, a
large number of scenarios are based on 3PE.
In a 3PE scenario, deploying BFD wastes resources. A large number of
single-homed PEs may be connected to the dual-homed PEs. The dua
Hi Reshad,
I agree with you that if in all the deployment scenarios there's always
only one node in a pair of nodes that needs to be aware of the path
continuity to the remote system, then S-BFD has an advantage compared to
"classic" RFC 5880-style BFD. I think that the use case presented in the

Hi Haibo and the Authors,
thank you for updating the draft. I've read the new version and have a
question about the use case presented in the document. There are three PEs
with two of them providing redundant access to a CE. It appears that a more
general case would be if both CEs use redundant con
