Hi Yisong, Changwang, Mengxiao,
After reading this draft, I think it's an interesting topic.
I have some comments here:
1. Where is the function deployed, only leaf node or both of leaf and spine
node?
2. According the example you mentioned in section 3.3, in case the link between
remote spine node and leaf node broken, how does the remote spine node know
which spine/leaf node should be notified, and which path should be carried in
the notification message?
3. The topology depolyed in DC which used for AI/HPC may be 3-level or 5-level
fat-tree, if there are many pods in the DC, there are plenty of routes and
paths in the network, right? How do you consider the scaling problem?
Thanks,
Sandy

Hi Everyone,
We have just submitted a draft on the rapid switchover of remote fault
perception. The link for this draft is:
https://datatracker.ietf.org/doc/draft-liu-rtgwg-path-aware-remote-protection/The
current main protection technologies include local protection through FRR,
such as TI-LFA protection, and end-to-end protection through multi-path
protection.In specific network scenarios, such as a spine-leaf two-layer
architecture, TI-LFA cannot be deployed, and even if it is deployed, traffic
will still loop during a fault. Therefore, this draft proposes a mechanism for
rapid switchover that is aware of remote paths. By associating the next hops
with remote path information at the forwarding plane, the local end can be
quickly notified to switch in the event of remote fault, achieving fault
switchover in milliseconds, or even microseconds.We welcome your feedback. If
you have any questions or comments, please feel free to let us know.
Best Regards
Yisong
