If a DR (Disaster Recovery) router fails, it can disrupt network connectivity and communication for connected devices, leading to potential downtime for services and applications reliant on that network. Depending on the network configuration, failover mechanisms may activate to switch to a backup router, minimizing service interruption. However, if no backup is available, recovery efforts will be necessary to restore functionality, which could involve troubleshooting or replacing the faulty router. It's crucial to have a robust disaster recovery plan in place to mitigate such risks.
The obvious answer is that the remote router is switched off !
When MBR fails then the operating system will not load.
Your router goes on then off, as many times as you turn it, on then off.

When OSPF routers have identical interface priorities, the tie is broken by the router IDs. The router with the highest router ID becomes the designated router (DR), while the one with the second-highest router ID becomes the backup designated router (BDR). The router ID is typically derived from the highest IP address assigned to an active interface or can be manually configured.
