Subject: [Ice] 5245bis: What is the state of a pair added to the valid list, if it is not the pair that generated the connectivity check?

Hi,

The text in section 6.1.2.4.2.2.  (Constructing a Valid Pair) of draft-5245bis describes how a pair, based on a successful connectivity check, is added to the valid list. It may be the pair that generated the check, it may be another pair in a check list, or it may be a pair not currently in any check list.

The text in section 6.1.2.4.2.3.  (Updating Pair States) says that the state of the pair that generated the check is set to Succeeded. The text then describes how the state of frozen pairs will be set to Waiting.

Q1: Assuming the pair being added to the valid list is not the pair that generated the check, what will the state of that pair be? I don't find any text about that. Shouldn't the state be set to Succeeded? It sounds strange to me to have pairs in e.g., Frozen or Waiting state in the valid list.

Regards,

Christer
