Enabling Layer 3 VSRP
15
Syntax: [no] backup [priority <value> ] [track-priority <value> ]
The backup 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.
4. Enable VSRP on the VRID.
BigIron RX(config-vlan-200-vrid-1)# enable
Syntax: [no] enable
or
Syntax: [no] activate
For information about the command’s optional parameters, see the following:
•
“Changing the backup priority” on page 422
•
“Changing the default track priority” on page 425
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.
BigIron RX(config)# router vsrp
Syntax: [no] router vsrp
•
If you want to provide Layer 3 redundancy only, you could use VRRP or VRRP-Extended. You
may use router vrrp or router vrrp-extended as long as router vsrp is not enabled.
Configuring optional VSRP parameters
The following sections describe how to configure optional VSRP parameters.
Disabling VSRP on a VRID
If you want to deactivate VSRP on a VRID, enter the following command.
BigIron RX(config-vlan-200-vrid-1)# disable
Syntax: disable
Configuring authentication
If the interfaces on which you configure the VRID use authentication, the VSRP packets on those
interfaces also must use the same authentication. VSRP supports the following authentication
types:
•
No authentication – The interfaces do not use authentication. This is the default.
