Hi Acee, > There was debate regarding making the delay timer described in section 5 a normative requirement.
I see added into new version of the draft the following text into section 5: The use of OSPF BFD strict- mode along with mechanisms such as hold-down *(a delay in the initial OSPF adjacency bringup following BFD session establishment)* and/or dampening *(a delay in the OSPF adjacency bringup following failure detected by BFD)* may help reduce the frequency of adjacency flaps and therefore reduce the associated routing churn. Not sure if this is normative or informative, but it addresses my point. Thx, Robert.
