Examples of VRRP Topologies

routing platform sends advertisements to backup routing platforms at regular intervals.
The default interval is 1 second. If the backup routing platforms do not receive an
advertisement for a set period, the backup routing platform with the highest priority takes
over as master and begins forwarding packets.
NOTE: Priority 255 cannot be set for routed VLAN interfaces (RVIs).
VRRP is defined in RFC 3768, Virtual Router Redundancy Protocol.
Figure 39 on page 1426 illustrates a basic VRRP topology with J-EX Series switches. In this
example, Switches A, B, and C are running VRRP and together they make up a virtual
routing platform. The IP address of this virtual routing platform is
address as the physical interface of Switch A).
Figure 39: Basic VRRP on J-EX Series Switches
Figure 40 on page 1427 illustrates a basic VRRP topology using Virtual Chassis
configurations. Switch A, Switch B, and Switch C are each composed of multiple
interconnected J-EX4200 Ethernet Switches. Each Virtual Chassis configuration operates
as a single switch, which is running VRRP, and together they make up a virtual routing
platform. The IP address of this virtual routing platform is
as the physical interface of Switch A).
