Chapter 43 Configuring IP Services
Virtual Router Redundancy Protocol
Note VRRP router authentication does not apply to IPv6.
To set an authentication option for a virtual router, follow these steps:
Priority Based on Interface State Tracking
Interface state tracking changes the priority of the virtual router based on the state of another interface
in the switch. When the tracked interface is down, the priority reverts to the priority value for the virtual
router (see the
“Priority for the Virtual Router” section on page 43-21 ). When the tracked interface is up,
the priority of the virtual router is restored to the interface state tracking value. You can track the state
of either a specified VSAN interface or the management interface (mgmt 0). The interface state tracking
feature is disabled by default.
Note
For interface state tracking to function, you must enable preemption on the interface. See the “Priority
Preemption” section on page 43-22 .
To track the interface priority for a virtual router using IPv4, follow these steps:
Command Purpose
Step 1
switch# config t
Enters configuration mode.
Step 2
switch(config)# interface vsan 1
switch(config-if)#
Configures a VSAN interface (VSAN 1).
Step 3
switch(config-if)# vrrp 250
switch(config-if-vrrp)#
Creates a virtual router.
Step 4
switch(config-if-vrrp)# authentication
text password
Assigns the simple text authentication option and
specifies the password for this option.
switch(config-if-vrrp)# authentication md5
password2003 spi 0x2003
Assigns the MD5 authentication option and
specifies the key and the unique SPI value for this
option. The SPI and the valid range is 0x100 to
0xFFFFFFFF.
switch(config-if-vrrp) # no authentication Assigns the no authentication option, which is the
default.
Command Purpose
Step 1
switch# config t
Enters configuration mode.
Step 2
switch(config)# interface vsan 10
switch(config-if)#
Configures a VSAN interface (VSAN 10).
Step 3
switch(config-if)# vrrp 250
switch(config-if-vrrp)#
Creates a virtual router.
Step 4
switch(config-if-vrrp)# preempt
Enables priority preemption.
Step 5
switch(config-if-vrrp)# track interface
mgmt 0 priority 2
Specifies the priority of the virtual router to be
modified based on the state of the management
interface.
switch(config-if-vrrp)# no track
Disables the tracking feature.
