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. See “Removing a Port from the VRID’s
VLAN” on page 8-30.
•
Configure a VRID.
•
Specify that the device is a backup. Since VSRP, like VRRPE, 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.
•
Activate the VRID.
The following example shows a simple VSRP configuration.
FastIron SuperX Router(config)# vlan 200
FastIron SuperX Router(config-vlan-200)# tag ethernet 1/1 to 1/8
FastIron SuperX Router(config-vlan-200)# vsrp vrid 1
FastIron SuperX Router(config-vlan-200-vrid-1)# backup
FastIron SuperX Router(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’s optional parameters, see the following:
•
“Changing the Backup Priority” on page 8-30
•
“Changing the Default Track Priority” on page 8-33
Syntax:
[no] activate
or
Syntax:
enable | disable
RIP Parameters
Suppression of
RIP
advertisements
A Layer 3 Switch that is running RIP normally
advertises routes to a backed up VRID even when the
Layer 3 Switch is not currently the active Layer 3
Switch for the VRID. Suppression of these
advertisements helps ensure that other Layer 3
Switches do not receive invalid route paths for the
VRID.
Note
: This parameter is valid only on Layer 3
Switches.
Disabled
(routes are advertised)
