router's configuration. Verify that you do not use this address for other interfaces,
for the IP address of a tunnel, or for the IP address of static ARP entries.
You cannot configure the same virtual IP address on interfaces that belong to the
same logical system and routing instance combination. However, you can configure
the same virtual IP address on interfaces that belong to different logical system and
routing instance combinations.
Priority for a router to become the master virtual router—Configure the value used to
elect the master virtual router in the VRRP group. It can be a number from 1 through
255. The default value for backup routers is 100. A larger value indicates a higher priority.
The router with the highest priority within the group becomes the master router.
NOTE: If there are two or more backup routers with the same priority, the
router that has the highest primary address becomes the master.
NOTE: Mixed tagging (configuring two logical interfaces on the same Ethernet
port, one with single-tag framing and one with dual-tag framing) is supported
only for interfaces on Gigabit Ethernet IQ2 and IQ PICs. If you include the
flexible-vlan-tagging
level for a VRRP-enabled interface on a PIC that does not support mixed
tagging, VRRP on that interface is disabled. In the output of the
command, the interface status is listed as

NOTE: If you enable MAC source address filtering on an interface, you must
include the virtual MAC address in the list of source MAC addresses that you
specify in the source-address-filter
hierarchy level. MAC addresses ranging from

00:00:5e:00:01:ff
IPv6, the MAC addresses range from
00:00:5e:00:02:ff
of the last hexadecimal byte of the virtual MAC address.
NOTE: For faster convergence, RFC recommends better difference of priorities
for VRRP routers. For example, if you have three routers in a VRRP group, it
is recommended to assign the router priority as:
Priority of master router as 254.
Priority of backup router 1 as 200.
Priority of backup router 2 as 150.
