Virtual Router Redundancy Protocol (VRRP)
Steps for Provisioning VRRP Operation
ProCurve(config)# router vrrp
ProCurve(config)# vlan 10
ProCurve(vlan-10)# vrrp vrid 1
ProCurve(vlan-10-vrid-1)# owner
ProCurve(vlan-10-vrid-1)# virtual-ip-address 10.10.10.1 255.255.255.0
ProCurve(vlan-10-vrid-1)# enable
ProCurve(vlan-10-vrid-1)# show vrrp vlan 10 vrid 1 config
VRRP Virtual Router Configuration Information
Vlan ID : 10
Virtual Router ID : 1
Administrative Status [Disabled] : Enabled
Mode [Uninitialized] : Owner
Priority [100] : 255
Advertisement Interval [1] : 1
Preempt Mode [True] : True
Primary IP Address : Lowest
IP Address Subnet Mask
--------------- ---------------
10.10.10.1 255.255.255.0
Because this router is the Owner, the priority is fixed
at 255 and cannot be changed.
For the same reason, the Preempt mode cannot be
changed.
Because there is only one virtual IP address
configured on the VR, the source address included
with advertisements from this VR is the same as the
virtual IP address for the VR.
This router is the Owner for VR 1 in VLAN 10.
Figure 6-3. VRRP Configuration for Router 1 (R1) in Figure 6-2, Above
ProCurve(config)# router vrrp
ProCurve(config)# vlan 10
ProCurve(vlan-10)# vrrp vrid 1
ProCurve(vlan-10-vrid-1)# backup
ProCurve(vlan-10-vrid-1)# virtual-ip-address 10.10.10.1/24
ProCurve(vlan-10-vrid-1)# enable
ProCurve(vlan-10-vrid-1)# show vrrp vlan 10 vrid 1 config
VRRP Virtual Router Configuration Information
Vlan ID : 10
Virtual Router ID : 1
Administrative Status [Disabled] : Enabled
Mode [Uninitialized] : Backup
Priority [100] : 100
Advertisement Interval [1] : 1
Preempt Mode [True] : True
Primary IP Address : Lowest
IP Address Subnet Mask
--------------- ---------------
10.10.10.1 255.255.255.0
Because this router is a Backup, the priority is set by
default to 100 and can be changed to manipulate the
precedence for Backup routers in the VR.
This router is a Backup in VR 1 for VLAN 10.
On a Backup router, the Preempt mode can be
changed. However, in a VR having only one backup,
Preempt mode has no effect.
