Will the configuration of an AR router be lost after the SRU is replaced
The configuration file of an AR router is stored in the storage medium of the SRU. For a single-control router, the configuration of a router is subject to the new SRU. For a dual-control router, the router automatically copies the configuration file to the standby SRU after the active SRU is switched over to the standby SRU.

Example of configuring VRRP active/standby backup on an AR router
The roadmap of configuring VRRP active/standby backup on an AR router to implement gateway redundancy is as follows: 1. Configure IP addresses and routing protocols for different device interfaces to enable network-layer connection among different devices. 2. Configure a VRRP group on Router A and Router B, respectively. Configure a high priority and set preemption delay to 20s on Router A and configure Router A as a master device to bear and forward traffic. Configure a low priority and configure Router B as a backup device to implement gateway redundancy. Configure a VRRP group. # Create VRRP 1 on Router A, set its priority to 120, and set the preemption delay to 20s. [RouterA] interface gigabitethernet 2/0/0 [RouterA-GigabitEthernet2/0/0] vrrp vrid 1 virtual-ip 10.1.1.111 //Configure a virtual IP address. [RouterA-GigabitEthernet2/0/0] vrrp vrid 1 priority 120 //Set priority to 120. [RouterA-GigabitEthernet2/0/0] vrrp vrid 1 preempt-mode timer delay 20 //Set the preemption delay to 20s. [RouterA-GigabitEthernet2/0/0] quit # Create VRRP 1 on Router B, and set its priority to a default value 100. [RouterB] interface gigabitethernet 2/0/0 [RouterB-GigabitEthernet2/0/0] vrrp vrid 1 virtual-ip 10.1.1.111 [RouterB-GigabitEthernet2/0/0] quit For details about the configuration, see the URL: Example for Configuring a VRRP Group in Active/Standby Mode.
