Line 8 sets the backup priority for virtual router VRID=1 to 200. Since this number is higher than Router R3’s backup priority for virtual router VRID=1, Router R2 is the primary Backup, and Router R3 is the secondary Backup for virtual router VRID=1.

On line 9, the backup priority for virtual router VRID=3 is set to 100. Since Router R1’s backup priority for this virtual router is 200, Router R1 is the primary Backup, and Router R2 is the secondary Backup for virtual router VRID=3.

The following table shows the priorities for each virtual router configured on Router R2.

Virtual Router	Default Priority	Configured Priority
VRID=1 – IP address=10.0.0.1/16	100	200 (see line 8)
VRID=2 – IP address=10.0.0.2/16	255 (address owner)	255 (address owner)
