VSRP
• Activate the VRID.
The following example shows a simple VSRP configuration.
Brocade(config)#vlan 200
Brocade(config-vlan-200)#tag ethernet 1/1 to 1/8
Brocade(config-vlan-200)#vsrp vrid 1
Brocade(config-vlan-200-vrid-1)#backup
Brocade(config-vlan-200-vrid-1)#activate
Syntax: [no] vsrp vrid <num>
The <num> parameter specifies the VRID and can be from 1 – 255.
Syntax: [no] backup [priority <value>] [track-priority <value>]
This command is required. In VSRP, all devices on which a VRID are configured are Backups. The
Master is then elected based on the VSRP priority of each device. There is no “owner” device as
there is in VRRP.
For information about the command optional parameters, refer to the following:
• “Changing the backup priority” on page 646
• “Changing the default track priority setting” on page 649
Syntax: [no] activate
or
Syntax: enable | disable
Configuring optional VSRP parameters
The following sections describe how to configure optional VSRP parameters.
Disabling or re-enabling VSRP
VSRP is enabled by default on Layer 2 Switches and Layer 3 Switches. On a Layer 3 Switch, if you
want to use VRRP or VRRP-E for Layer 3 redundancy instead of VSRP, you need to disable VSRP
first. To do so, enter the following command at the global CONFIG level.
Brocade(config)#no router vsrp
router vsrp is disabled. All vsrp config data will be lost when writing to flash
To re-enable the protocol, enter the following command.
Brocade(config)#router vsrp
Syntax: [no] router vsrp
Since VRRP and VRRP-E do not apply to Layer 2 Switches, there is no need to disable VSRP and
there is no command to do so. The protocol is always enabled.
