Basic VRRP parameter configuration
Note regarding disabling VRRP or VRRP-E
If you disable VRRP or VRRP-E, the Layer 3 switch removes all the configuration information for the
disabled protocol from the running-config file. Moreover, when you save the configuration to the
startup-config file after disabling one of these protocols, all the configuration information for the
disabled protocol is removed from the startup-config file.
The CLI displays a warning message such as the following.
Brocade Router1(config-vrrp-router)#no router vrrp
router vrrp mode now disabled. All vrrp config data will be lost when writing to
flash!
If you have disabled the protocol but have not yet saved the configuration to the startup-config file
and reloaded the software, you can restore the configuration information by re-entering the
command to enable the protocol (for example, router vrrp). If you have already saved the
configuration to the startup-config file and reloaded the software, the information is gone.
If you are testing a VRRP or VRRP-E configuration and are likely to disable and re-enable the
protocol, you may want to make a backup copy of the startup-config file containing the protocol
configuration information. This way, if you remove the configuration information by saving the
configuration after disabling the protocol, you can restore the configuration by copying the backup
copy of the startup-config file onto the flash memory.
Basic VRRP parameter configuration
To implement a simple VRRP configuration using all the default values, enter the commands shown
in the following sections.
Configuration rules for VRRP
• The interfaces of all routers in a VRID must be in the same IP subnet.
VRRP-E slow
start timer Causes a specified amount of time to elapse between the
time the original Master is restored and when it takes over
from the Backup. This interval allows time for OSPF
convergence when the Master is restored. For VRRP-E
only. Disabled page 441
Short-path
forwarding Enables VRRP-E extension for server virtualization. If
enabled, the traffic that is destined to the clients travels
through the short-path forwarding path to reach the client
(as shown in
Figure 33 on page 443). Any packets coming
from the local subnet of the virtual IP address are
forwarded either by the VRRP-E master router or VRRP-E
backup router depending on which router received the
packets.
