By configuring the Virtual Router Redundancy Protocol (VRRP) on EX Series switches,
you can enable hosts on a LAN to make use of redundant routing platforms on that LAN
without requiring more than the static configuration of a single default route on the hosts.
You can configure VRRP for IPv6 on Gigabit Ethernet, 10-Gigabit Ethernet, and logical
interfaces.
To configure VRRP for IPv6:
Configure VRRP group support on interfaces:
1.
[edit interfaces interface-name unit logical-unit-number family inet6
address address]
user@switch# set vrrp-inet6-group group-id priority number virtual-inet6-address
address virtual-link-local-address ipv6-address
You must explicitly define a virtual link local address for each VRRP for IPv6 group.
Otherwise, when you attempt to commit the configuration, the commit request fails.
The virtual link local address must be on the same subnet as the physical interface
address.
If you want to configure the priority order in which this switch functioning as a backup
2.
router becomes the master router if the master router becomes nonoperational,
configure a priority for this switch:
[edit interfaces interface-name unit logical-unit-number family inet6
address address vrrp-inet6-group group-id]
user@switch# set priority number
Specify the interval in milliseconds in which the master router sends advertisement
3.
packets to the members of the VRRP group:
