11.6.4 Configuration of Virtual Router Redundancy Protocol (VRRP)
VRRP is designed for backup of routers acting as default gateways. This is achieved by joining IP
interfaces of the group of routers into one virtual interface which will be used as the default gateway for
the computers of the network. On a channel layer the reserved interfaces have MAC address
00:00:5E:00:01:XX, where XX is the number of the VRRP (VRID) group.
Only one physical router can route the traffic on a virtual IP interface (VRRP master), the rest of
routers in the group are designed for backup (VRRP backup). VRRP master is selected as per RFC 5798. If
the current master becomes unavailable, a new master is selected. The highest priority belongs to router
with own IP address which matches the virtual one. If it is available, it always becomes a VRRP master. The
maximum number of VRRP processes is 50.

Table 5.233. Ethernet, VLAN, port group interface configuration mode commands
Command
Value/Default value
Action
vrrp vrid description text
vrid: (1..255);
text: (1..160 digits).
Add goal description or use for a VRRP router with the vrid
identifier.
no vrrp vrid description
Delete description of a VRRP router.
vrrp vrid ip ip_address
vrid: (1..255)
Specify the IP address of a VRRP router.
no vrrp vrid ip [ip_address ]
Delete the IP address of a VRRP. If no parameters are given, then
all IP addresses of the virtual router are removed, and as a result
of which the virtual router vrid will be removed from the device.
vrrp vrid preempt
vrid: (1..255);
Enabled by default
Enable the mode in which a backup router with higher priority
will try to take the role of a master from the current master
router with lower priority.
The router which is owner of the virtual IP address will
take the role of a master regardless of the settings in
this command.
no vrrp vrid preempt
Set the default value.
vrrp vrid priority priority
vrid: (1..255);
priority: (1..254);
By default: 255 for the
owner of the IP address,
100 for the rest
Set the VRRP router priority.
no vrrp vrid priority
Set the default value.
vrrp vrid shutdown
vrid: (1..255);
By default: disabled
Disable VRRP on this interface
no vrrp vrid shutdown
Enable VRRP on this interface
vrrp vrid source-ip
ip_address
vrid: (1..255);
By default: 0.0.0.0
Set of the real VRRP address that will be used as the IP address
of the sender for VRRP messages.
no vrrp vrid source-ip
Set the default value.
vrrp vrid timers advertise
{seconds | msec
milliseconds}
seconds: (1..40);
milliseconds: (50..40950);
By default: 1 sec
Specify the interval between master router announcements. If
the interval is set in milliseconds, it is rounded off down to
closest seconds for VRRP Version 2 and to closest hundredths
second (10 milliseconds) for VRRP Version 3.
no vrrp vrid timers
advertise [msec]
Set the default value.
