Hi WG， We have submitted a new version according to the comments in last IETF meeting. Thanks a lot for Terek Saad and Jeffery Zhang for their valuable comments.
1. For the question from Terek Saad what happens when the egress PE to CE link fails? We have updated the draft as below: If a failure occurs on the link between egress PE and CE, that PE should work as the local repair node and forward packet to another Egress PE node. It can be achieved by using the tunnel towards another PE as an alternate next-hop for the routes to CE with FRR mechanism, while the failed link is the primary next-hop. The alternate next-hop can be installed as an SRv6 BE path when receiving the BGP routes of the same service from another egress PE. 2. For the question from Jeffrey Zhang what is the difference from SR? We think this document mainly focuses on the reliability solution of SRv6 network. As an operator, I think SRv6 is very important for our network deployment, and how to deploy the corresponding protection mechanism is what we are more concerned about. We hope to get more feedback for the WG. If you have any comments or questions, please don't hesitate to let us know.
