Configuration Guide - IP Routing
interface connected to the RSG is associated with the VRRP backup group, enabling the cost of
the direct route to the network segment where the interface resides to change based on the VRRP
status. VRRP for direct routes works as follows:

If the VRRP status becomes Backup, the direct route's cost increases, lowering the direct
route's priority level. The direct route will no longer be an optimal route.
If the VRRP status becomes Master, the direct route's cost is set to 0, allowing the direct
route's priority to be the highest. The direct route will be an optimal route.

Configure OSPF on the CSG, UPE1, UPE2, and the RSG.
Create backup group 1 on GE 2/0/0 of UPE1, and assign a priority higher than the default
one to UPE1 so that UPE1 will function as the master.
Create backup group 1 on GE 2/0/0 of UPE2, and set the default priority for UPE2 so that
UPE2 will function as the backup.
Associate GE 2/0/0 on UPE1 with backup group 1, enabling the cost of the direct route to
the network segment where GE 2/0/0 resides to change based on the VRRP status.
