1. SRv6 Path Egress Protection

Publication URL: https://datatracker.ietf.org/doc/html/draft-ietf-rtgwg-srv6-egress-protection


This document describes protocol extensions for protecting the egress node of a Segment Routing for IPv6 (SRv6) path or tunnel.

2. SR-TE Path Midpoint Protection

Publication URL: https://datatracker.ietf.org/doc/html/draft-hu-spring-segment-routing-proxy-forwarding


This document describes a mechanism that allows traffic to continue to be forwarded on an SR-TE path for an extended period of time after the failure of a node used in the path’s segment list.

3. SRv6 Midpoint Protection

Publication URL: https://datatracker.ietf.org/doc/html/draft-chen-rtgwg-srv6-midpoint-protection/


This document defines midpoint protection, which enables the direct neighbor of the failed endpoint to do the function of the endpoint, replace the IPv6 destination address to the other endpoint, and choose the next hop based on the new destination address.

4. Enhanced TI-LFA (TI-LFA+)

Publication URL: https://datatracker.ietf.org/doc/html/draft-li-rtgwg-enhanced-ti-lfa


This document defines Enhanced TI-LFA(TI-LFA+) by adding a No-bypass indicator for segments to ensure that the FRR route will not bypass the specific node, such as firewall. Also, this document defines No-bypass flag and No-FRR flag in SRH to indicate not to bypass nodes and not to perform FRR on all the nodes along the SRv6 path, respectively.

5. Considerations for Protection of SR Networks

Publication URL: https://datatracker.ietf.org/doc/draft-liu-rtgwg-sr-protection-considerations/


This document describes the considerations for protection of Segment Routing (SR) networks.


1. Technical requirement of SRv6 Protection


This is the standard project in CCSA which defines the SRv6 protection technology and procedure. The document has been approved by the WG.

2. Test requirement of SRv6 Protection


CCSA TC3WG2 has just approved the project, according to the technologies defined in “Test requirement of SRv6 Protection”.
