Physical routers comprising
one virtual Router in VRRP
Master
Backup
Office
Hosts unaware that more
than one physical router
exist
Configuration
VRRP can be enabled on select interfaces, including Ethernet, Bridge, and VLAN interfaces. For
example:
configure
%set interfaces interface ETH2 vrrp address 192.168.1.1 subnet-mask 255.255.255.0 id 1
priority 100
The following items are configurable VRRP settings for each interface:
 enabled – whether or not VRRP is enabled on the interface
 address – the Virtual IP (VIP) assigned to the physical routers in a VRRP group.
 subnet-mask – corresponding subnet-mask to the VIP
 id – a numeric value that indicates which VRRP group this router belongs to.
 priority – each physical router in a group gets its own priority. The higher the number, the
higher the priority that the physical router will be become the Master during negotiation.
 advertisement-interval – The Master router advertises its presence to the Backups. This
controls the frequency of those advertisements.
 preemption – whether or not to allow higher priority routers become Master when they come
online.
All physical routers in a VRRP group must be configured with same VIP address/subnet and id. Each
router should have a unique priority value. Lastly, each router could have an additional, unique, IP/subnet
on the same interface that VRRP is running on to facilitate administration and diagnostics.
Monitoring
Read-only parameters for interfaces with VRRP show the state of the router:
show interfaces-state interface ETH2 vrrp
The router status will be displayed as one of the following states:
vrrp disabled – VRRP is disabled on this interface.
vrrp initializing – VRRP is starting.
