To address the issue raised by the ticket please add the following to the beginning of 6.3:

When an ETR becomes unreachable (e.g., due to the ETR crash), that results in (temporary) black-holing the traffic that have been sent to that ETR by ITRs, which in turn may result in service disruption. That black-holing and the service disruption due to that black-holing lasts until all these ITRs determine that the ETR is no longer reachable, and subsequently select another ETR.
