VRRP configuration
The communications within one VLAN is done by using the access layer switches.
Inter-VLAN communications is done by using aggregation layer switches (AGG-1, AGG2)
configured with VRRP groups for different VLANs.
The VRRP priorities should be kept in-line with STP bridge priorities, that is, the STP root
bridge should be the VRRP active router. Table 3-17 shows the VRRP priorities.
