include the virtual MAC address in the list of source MAC addresses that you
specify in the

Network Interfaces Library for Routing Devices
00:00:5e:00:01:00 through 00:00:5e:00:01:ff are reserved for VRRP, as
defined in RFC 2378. The VRRP group number must be the decimal equivalent
of the last hexadecimal byte of the virtual MAC address.
Here are specific examples of configuring a VRRP group.
To configure basic VRRP (IPv4) groups on interfaces:
NOTE: You can also configure a VRRP IPv4 group at the
logical-system-name]
Configure the group identifier.
1.
[edit interfaces interface-name unit logical-unit-number family inet address address]
user@device# set vrrp-group group-id
Assign a value from 0 through 255.
Configure the VRRP for IPv4 group:
2.
Configure the virtual IP address of one or more virtual routers that are members of
the VRRP group.
[edit interfaces interface-name unit logical-unit-number family inet address address]
user@device# set vrrp-group group-id virtual-address [ addresses ]
Normally, you configure only one virtual IP address per group. However, you can
configure up to eight addresses. Do not include a prefix length in a virtual IP address.
Configure the priority for this routing platform to become the master virtual router.
[edit interfaces interface-name unit logical-unit-number family inet address address]
user@device# set vrrp-group group-id priority number
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 routing platform with the highest priority within
the group becomes the master router. If there are two or more backup routers with
the same priority, the router that has the highest primary address becomes the
master.
