It would be interesting to know whether the switches were running NSR for some or all protocols, to get a feeling for whether the failure cascading from one RP to the other was partially due to that. I can't find definitive information on the current state of state replication technology with Cisco, but I know that with Juniper on current code on the MX, state is not replicated between RE's, but rather, the main RE proxies protocol state machines to the backup RE and only when the backup RE is "ESTABLISHED" (again, by proxy via the main RE) does the main RE also establish with its neighbor. So state isn't simply replicated, to avoid bug related cascades. Mark.
