Configuring Active-Active VRRP
Procedure
Step1Â Â Â Â Â Â Â Â Configure Layer 3 interface. VRRP can be enabled on a VLAN interface or a routed interface.
- Configure a VLAN interface.
  a)     Configure VLAN ID.
  set vlans vlan-id <vlan-id>
  b)    Configure the interface to VLAN.
  set interface gigabit-ethernet <port> family ethernet-switching native-vlan-id <vlan-id>
  c)     Configure the IP address of the VLAN.
  set l3-interface vlan-interface <interface-name> address <address> prefix-length <number>
  d)    Associate a Layer 3 interface with a VLAN.
  set vlans vlan-id <vlan-id> l3-interface <interface-name>
- Configure a routed interface.
   a)     Enable routed interface.
   set interface gigabit-ethernet <interface-name> routed-interface enable <true | false>
  set interface gigabit-ethernet <interface-name> routed-interface name <string>
  b)    Configure reserved-vlan for the routed interface. Â
  set vlans reserved-vlan <reserved-vlan>
  c)   (Optional) Create the sub-interface and add it into a VLAN.
  set interface aggregate-ethernet <interface-name> routed-interface sub-interface <sub-interface-name> vlan-id <vlan-id>
  d)     Configure the IP address of the routed interface.
   set l3-interface routed-interface <interface-name> address <ip-address> prefix-length <prefix-number>
Step2Â Â Â Â Â Â Â Â Â Create a VRRP group.
          set protocols vrrp interface <interface-name> vrid <virtual-router-id>
NOTE:
|
Step3Â Â Â Â Â Â Â Â Â Configure the VRRP version number.
  set protocols vrrp interface <interface-name> vrid <virtual-router-id> version <2 | 3>
  By default, the system uses VRRPv2.
Step4Â Â Â Â Â Enable the VRRP function.
  set protocols vrrp interface <interface-name> vrid <virtual-router-id> disable <true | false>
  By default, the VRRP function is enabled. Currently, VRRP can be configured on the VLAN interfaces or routed interfaces.
Step5Â Â Â Â Â Â Â Â Enable the Active-Active VRRP function.
             set protocols vrrp interface <interface-name> vrid <virtual-router-id> load-balance disable <true | false>          Â
NOTE:
|
Step6Â Â Â Â Â Â Â Â Â Configure a virtual IP address for the VRRP group.
          set protocols vrrp interface <interface-name> vrid <virtual-router-id> ip <ipv4-address>
NOTE:
|
Step7Â Â Â Â Â (Optional) Configure the interval of sending VRRP advertisement packets.
  set protocols vrrp interface <interface-name> vrid <virtual-router-id> interval <interval-value>
NOTE:
|
Step8Â Â Â Â Â Â Â Â Â (Optional) Configure VRRP preemptive mode.
          set protocols vrrp interface <interface-name> vrid <virtual-router-id> preempt enable <true | false>
          By default, preemptive mode is enabled.
Step9Â Â Â Â Â Â Â Â (Optional) Configure the interval of updating the virtual MAC.
         set protocols vrrp interface <interface-name> vrid <virtual-router-id> load-balance virtual-MAC time-interval <interval-value>
Step10Â Â Â Â Â (Optional) Configure the priority of the device in a VRRP group.
          set protocols vrrp interface <interface-name> vrid <virtual-router-id> priority <priority-value>
          By default, the priority of the device in a VRRP group is 100.
Step11Â Â Â Â Â (Optional) Configure an authentication mode and authentication key for a VRRP group. Note that VRRP authentication is only supported by VRRPv2, which is not supported by VRRPv3.
  set protocols vrrp interface <interface-name> vrid <virtual-router-id> authentication type <none | md5 | simple>
  set protocols vrrp interface <interface-name> vrid <virtual-router-id> authentication simple-key <simple-key>
  set protocols vrrp interface <interface-name> vrid <virtual-router-id> authentication md5-key <md5-key>
Step12Â Â Â Â Â (Optional)Â Enable accept mode.
  set protocols vrrp interface <interface-name> vrid <virtual-router-id> accept disable <true | false>
NOTE:
|
Step13     (Optional) Configure the paremeters for sending router advertisement messages.
  set protocols vrrp interface <interface-name> vrid <virtual-router-id> ipv6-nd xx
