All,
I have a question regarding the State Synchronization process. Let's say, for example, the PEP has reconnected to the PDP after a connection failure and the PDP does not have memory of the PEP installed state. Therefore, the PDP issues a SSQ without a client-handle in order to become synchronized with the PEP. Now, during the synchronization process, the PEP sends a REQ with client specific information about a interface-type/role combo that the PDP has no knowledge of and the PDP sends a DEC specifying an error. My specific question is: Should the PEP send an SSC if it receives a DEC error? The RFC only states that after the PEP completes the synchronization it will send an SSC. In my opinion, the state is not synchronized if the PEP has installed state that the PDP does not have installed. I can think of other paths which can be taken but they are beyond the scope of this question.
