Configuring VRRP
DETAILED STEPS
Configuring VRRP Authentication
You can configure simple text authentication for a VRRP group.
BEFORE YOU BEGIN
Command Purpose
Step 1
config t
Example:
switch# config t
switch(config)#
Enters configuration mode.
Step 2
interface interface-type slot/port
Example:
switch(config)# interface ethernet 2/1
switch(config-if)#
Enters interface configuration mode.
Step 3
vrrp number
Example:
switch(config-if)# vrrp 250
switch(config-if-vrrp)#
Creates a virtual router group.
Step 4
shutdown
Example:
switch(config-if-vrrp)# shutdown
switch(config-if-vrrp)#
Disables the VRRP group. Disabled by default.
Step 5
priority level [forwarding-threshold lower
lower-value upper upper-value ]
Example:
switch(config-if-vrrp)# priority 60
forwarding-threshold lower 40 upper 50
Sets the priority level used to select the active
router in an VRRP group. The level range is
from 1 to 254. The default is 100 for backups
and 255 for a master that has an interface IP
address equal to the virtual IP address.
Optionally, sets the upper and lower threshold
values used by vPC to determine when to fail
over to the vPC trunk. The lower-value range is
from 1 to 255. The default is 1. The upper-value
range is from 1 to 255. The default is 255.
Step 6
no shutdown
Example:
switch(config-if-vrrp)# no shutdown
switch(config-if-vrrp)#
Enables the VRRP group. Disabled by default.
Step 7
show vrrp
Example:
switch(config-if-vrrp)# show vrrp
(Optional) Displays a summary of VRRP
information.
Step 8
copy running-config startup-config
Example:
switch(config-if-vrrp)# copy running-config
startup-config
(Optional) Saves this configuration change.
