How to Configure Virtual Router Redundancy Protocol (VRRP) on Dell Networking PowerConnect switches

1.  Overview

2.  Configuration

3.  Verify Configuration

 

 

 

VRRP allows multiple routers to provide active/passive redundancy for a routing IP address used by devices on a broadcast domain.
 

 

You will need to complete configuration on both physical devices that are selected for the VRRP installation.

NOTE: Prior configuration of ports on the switches to establish a trunk that will allow VLAN traffic to pass between the two switches is required.

NOTE:  You will need to ensure that the IP interface/VLAN is reachable from both switches. If not the both switches will come up as PRIMARY. VRRP hellos are sent thru Multicast and all protocol messaging is performed using IP multicast datagrams.

 

Router 1

 

Command	Purpose
R1(config)# ip routing R1(config)# ip vrrp	Enable routing on the switch using the ip routing command and use the ip vrrp command to enable the VRRP routing protocol on the switch.
R1(config)# interface vlan 10 R1(config-if-vlan10)# ip address 10.10.10.2 /24	Enter the selected VLAN interface and assign an IP address.
R1(config-if-vlan10)# vrrp 1	Set the VRID for the group.
R1(config-if-vlan10)# vrrp 1 10.10.10.1	Set the virtual IP address for the VRRP router.
R1(config-if-vlan10)# vrrp 1 mode R1(config-if-vlan10)# vrrp 1 priority 20	Use the vrrp 1 mode command to activate the VRRP router.  Use the vrrp 1 priority command to set the priority for primary election.  Range 1-254.

 

Command	Purpose
R2(config)# ip routing R2(config)# ip vrrp	Enable routing on the switch using the ip routing command and use the ip vrrp command to enable the VRRP routing protocol on the switch.
R2(config)# interface vlan 10 R2(config-if-vlan10)# ip address 10.10.10.3 /24	Enter the selected VLAN interface and assign an IP address.
R2(config-if-vlan10)# vrrp 1	Set the VRID for the group.
R2(config-if-vlan10)# vrrp 1 10.10.10.1	Set the virtual IP address for the VRRP router.
R2(config-if-vlan10)# vrrp 1 mode R2(config-if-vlan10)# vrrp 1 priority 200	Use the vrrp 1 mode command to activate the VRRP router.  Use the vrrp 1 priority command to set the priority for primary election.  Range 1-254.

NOTE:  If two routers in a VRRP group come up at the same time and have the same priority value, the interface's physical IP addresses are used as tie-breakers to decide which is Primary. The router with the higher IP address becomes Primary.
