Technical Summary This document specifies extensions to OSPF Router Informational (RI) to for an OSPF router to advertise its Seamless BFD discriminators. The scope of an advertisement can be an OSPF area or the entire OSPF routing domain. The architecture for seamless BFD is described in "Seamless Bidirectional Forwarding Detection (S-BFD)" - draft-ietf-bfd-seamless-base-05. Working Group Summary The document is an adjunct to the Seamless-BFD work being done in the BFD WG. It is very straight-forward and there hasn't been many comments. During WG last call, it was noted that the behavior must be specified when there are multiple instances of the S-BFD discriminator TLV. This comment was subsequently handled. The question of multiple S-BFD discriminators was also discussed in reference to the base Seamless BFD draft. This results in much discussion with appropriate text added to the base document indicating that this was basically a local matter and outside the scope of the standard. Document Quality This document has been a WG document for some time and is being advanced now that the seamless BFD work is being advanced in the BFD working group. Personnel Acee Lindem is the Document Shepherd. Alia Atlas is the Responsible Area Director.
