Configuring Optional VSRP Parameters

VSRP is enabled after assigning a Virtual Routing ID (VRID) on specific ports in a port-based VLAN and setting a backup priority for the device. You can configure a number of optional parameters to customize your VSRP configuration after VSRP is enabled.

VSRP is configured and enabled.

Note: VSRP is enabled by default on RUCKUS devices, but may be disabled if Virtual Router Redundancy Protocol (VRRP) or VRRP Extended (VRRP-E) is currently enabled.
Note: All the steps in this section are optional.
  1. On any device on which you want to configure, from privileged EXEC mode, enter global configuration mode by issuing the configure terminal command. 
    device# configure terminal
  2. Configure a VLAN by assigning an ID to the VLAN. 
    device(config)# vlan 200
  3. Assign a VSRP VRID to the VLAN. 
    device(config-vlan-200)# vsrp vrid 200
  4. Configure a Backup to save the VSRP timer values received from the Master instead of the timer values configured on the Backup. 
    device(config-vlan-200-vrid-200)# save-current-values
  5. Configure how many hops the packet can traverse before being dropped. 
    device(config-vlan-200-vrid-200)# initial-ttl 5
  6. Configure the number of seconds between Hello messages from the Master to the backups for a given VRID. 
    device(config-vlan-200-vrid-200)# hello-interval 10
  7. Configure the number of seconds a backup waits for a Hello message from the Master before determining that the Master is offline. 
    device(config-vlan-200-vrid-200)# dead-interval 15
  8. Configure the interval for the backup to send Hello messages to the Master when the advertisement is enabled. 
    device(config-vlan-200-vrid-200)# backup-hello-interval 180
  9. Change the hold-down time interval.
    The hold-down interval prevents Layer 2 loops from occurring during failover, by delaying the new Master from forwarding traffic long enough to ensure that the failed Master is really unavailable. 
    device(config-vlan-200-vrid-200)# hold-down-interval 4
  10. Change the timer scale for all the timers while preserving the ratios among their values. Increasing the timer scale value decreases the length of all the VSRP timers equally.
    device(config-vlan-200-vrid-200)# exit
device(config)# scale-timer 2
  11. Add additional ports to the VSRP instance.
    device(config-vlan-200-vrid-200)# include-port ethernet 1/1/10
  12. Configure VRID IP address if you are configuring Layer 3 redundancy.
    device(config-vlan-200-vrid-200)# ip-address 10.10.10.1

    VSRP does not require you to specify an IP address. If you do not specify an address, VSRP provides Layer 2 redundancy. If you specify an IP address, VSRP provides Layer 2 and Layer 3 redundancy.
