手順

This article explains how to configure Virtual Router Redundancy Protocol (VRRP) on Dell Networking OS9 switches.

Overview

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

  • VRRP Primary - responds to the virtual IP address
  • VRRP Backup - elected as the primary if advertisements from the primary are no longer detected and begins responding to the virtual IP address
  • Virtual Router Identifier (VRID) - configured to match between VRRP routers

Configuration Overview

  1. Configure a VRRP group and specify a VRID on an interface (physical or VLAN) in L3 mode with an IP address assigned.
  2. Configure a virtual IP address for the VRRP group.
  3. Optional - Configure VRRP Priority.

Configuration

Router 1
Command Purpose 
R1# configure
 Enter configuration mode. 
R1(conf)# interface VLAN 10
 Enter an interface (physical or VLAN). 
R1(conf-if-vl-10)#  ip address 10.10.10.2 /24
R1(conf-if-vl-10)#  no shutdown
 Set an IP address on the interface and enable for L3 mode. 
R1(conf-if-vl-10)#  vrrp-group 10
 Set VRRP group ID (VRID). 
R1(conf-if-vl-10-vrid-10)#  virtual-address 10.10.10.1
 Set a Virtual IP address for the VRRP router.  
R1(conf-if-vl-10-vrid-10)#  priority 200
 (Optional) Set priority for Primary election, the default is 100, the higher number takes priority, Range 1-255.

Router 2
Command Purpose 
R2# configure
 Enter configuration mode. 
R2(conf)# interface VLAN 10
 Enter an interface (physical or VLAN). 
R2(conf-if-vl-10)#  ip address 10.10.10.3 /24
R2(conf-if-vl-10)#  no shutdown
 Set an IP address on the interface and enable for L3 mode. 
R2(conf-if-vl-10)#  vrrp-group 10
 Set VRRP group ID (VRID) 
R2(conf-if-vl-10-vrid-10)#  virtual-address 10.10.10.1
 Set a Virtual IP address for the VRRP router.  
R2(conf-if-vl-10-vrid-10)#  priority 150
 (Optional) Set priority for Primary election, the default is 100, the higher number takes priority, Range 1-255.

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