[Lsr] I-D Action: draft-ietf-ospf-ospfv2-hbit-08.txt
A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Link State Routing WG of the IETF. Title : Host Router Support for OSPFv2 Authors : Keyur Patel Padma Pillay-Esnault Manish Bhardwaj Serpil Bayraktar Filename: draft-ietf-ospf-ospfv2-hbit-08.txt Pages : 10 Date: 2019-07-08 Abstract: The OSPFv2 specifies an SPF algorithm that identifies transit vertices based on their adjacencies. Therefore, OSPFv2 does not have a mechanism to prevent traffic transiting a participating node if it is a transit vertex in the only existing or shortest path to the destination. The use of metrics to make the node undesirable can only help to repel traffic if an alternative better route exists. This document defines the Host-bit functionality to prevent other OSPFv2 routers from using the router for transit traffic in OSPFv2 routing domains. This document updates the Open Shortest Path First v2 specification (OSPFv2 rfc2328) by assigning a new bit (Host-bit) in the OSPF Router-LSA bit registry. In addition, if the Host-bit is set, the calculation of the shortest-path tree for an area, as described in OSPFv2, is modified by including a new check to verify that transit vertices have the Host-bit clear. In addition, this document updates OSPF Stub Router Advertisement (rfc6987) to advertise for type-2 External and NSSA LSAs with a high cost in order to repel traffic effectively.

[Lsr] Update for draft-ketant-lsr-ospf-bfd-strict-mode-02.txt
Hello All, We've posted an update for the OSPF Strict Mode for BFD operations that incorporates feedback and inputs received from WG members. Mainly : 1) Strict Mode working for OSPFv3 IPv4 AF instances 2) Clarifications on interactions with GR operations We would welcome further review/comments/feedback/contributions from the WG.

The signaling of this BFD enablement, allows the router to block and not allow the establishment of adjacency with its neighbor router until a BFD session is successfully established between them. The document describes this OSPF "strict-mode" of BFD establishment as a prerequisite to adjacency formation.

[Lsr] Update to OSPFv3 SRv6 extensions draft for review/feedback
Hello All, We've posted an update to the OSPFv3 SRv6 specifications that is now aligned with the ISIS SRv6 spec that was adopted by the WG (https://datatracker.ietf.org/doc/draft-ietf-lsr-isis-srv6-extensions/). We welcome comments and feedback from the WG.

Segment routing architecture can be implemented over an MPLS data plane as well as an IPv6 data plane. This draft describes the OSPFv3 extensions required to support Segment Routing over an IPv6 data plane (SRv6).
