Workaround: If no preempt is configured for a vlan in VRRP, the default advertisement timer should be changed to 8 seconds to avoid the incorrect role. This change must be done on both the Master and Backup routers only for the vlan where no preempt is configured.
This example shows vlan 22:
configure terminal router vrrp interface vlan 22 no vrrp 2 preempt vrrp 2 timer 8 end copy running-config startup-config
