<vrid number> is a valid VRID (from 1 to 255).
no-auth
specifies no authentication as the preferred VSRP-aware security method. The VSRP device will not
accept incoming packets that have authentication strings.
simple-text-auth
<string> specifies the authentication string for accepting VSRP hello packets, where <string>
can be up to 8 characters.
port-list
<port range> specifies the range of ports to include in the configuration.
Removing a Port from the VRID’s VLAN
By default, all the ports in the VLAN on which you configure a VRID are interfaces for the VRID. You can remove
a port from the VRID while allowing it to remain in the VLAN.
Removing a port is useful in the following cases:
•
There is no risk of a loop occurring, such as when the port is attached directly to an end host.
•
You plan to use a port in an MRP ring.
To remove a port from a VRID, enter a command such as the following at the configuration level for the VRID:
FastIron SuperX Router(config-vlan-200-vrid-1)# no include-port ethernet 1/2
Syntax:
[no] include-port ethernet [<slotnum>/]<portnum>
The <slotnum> parameter is required on chassis devices.
The <portnum> parameter specifies the port you are removing from the VRID. The port remains in the VLAN but
its forwarding state is not controlled by VSRP. If you are configuring a chassis device, specify the slot number as
well as the port number (<slotnum>/<portnum>).
Configuring a VRID IP Address
If you are configuring a Layer 3 Switch for VSRP, you can specify an IP address to back up. When you specify an
IP address, VSRP provides redundancy for the address. This is useful if you want to back up the gateway address
used by hosts attached to the VSRP Backups.
VSRP does not require you to specify an IP address. If you do not specify an address, VSRP provides Layer 2
redundancy. If you do specify an address, VSRP provides Layer 2 and Layer 3 redundancy.
The Layer 3 redundancy support is the same as VRRPE support. For information, see the chapter “Configuring
VRRP and VRRPE” on page 22-1.
NOTE:
The VRID IP address must be in the same subnet as a real IP address configured on the VSRP interface,
but cannot be the same as a real IP address configured on the interface.
NOTE:
Failover applies to both Layer 2 and Layer 3.
To specify an IP address to back up, enter a command such as the following at the configuration level for the
VRID:
FastIron SuperX Router(config-vlan-200-vrid-1)# ip-address 10.10.10.1
Syntax:
[no] ip-address <ip-addr>
or
Syntax:
[no] ip address <ip-addr>
Changing the Backup Priority
When you enter the backup command to configure the device as a VSRP Backup for the VRID, you also can
change the backup priority and the track priority.
•
The backup priority is used for election of the Master. The VSRP Backup with the highest priority value for the
VRID is elected as the Master for that VRID. The default priority is 100. If two or more Backups are tied with
