Configuring basic VSRP parameters
To configure VSRP, perform the following required tasks:
• Configure a port-based VLAN containing the ports for which you want to provide VSRP service.
NOTE
If you already have a port-based VLAN but only want to use VSRP on a sub-set of the VLANs
ports, you can selectively remove ports from VSRP service in the VLAN. Refer to
“Removing a
port from the VRID’s VLAN” .
• Configure a VRID:
• Specify that the device is a backup. Since VSRP, like VRRP-E, does not have an “owner”, all
VSRP devices are backups. The active device for a VRID is elected based on the VRID
priority, which is configurable.
• Enable VSRP on 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)# enable
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’s optional parameters, refer to the following:
• “Changing the backup priority”
• “Changing the default track priority”
Syntax: [no] enable | disable
Note on VSRP support when using ESI
VSRP is supported only for VLANs that are part of the default ESI. VSRP is not supported for VLANs
configured under user-defined ESIs.
Configuring optional VSRP parameters
The following sections describe how to configure optional VSRP parameters.
Enabling Layer 3 VSRP
Layer 2 VSRP is enabled globally by default on the device; it just needs to be activated or enabled
on a VRID. If you want to use Layer 3 VSRP, you must enable it by entering the following command
at the CONFIG level.
