the key factor in the successful deployment of IPv6. Because millions of IPv4 nodes
already exist, upgrading every node to IPv6 at the same time is not feasible.
As a result, transition from IPv4 to IPv6 happens gradually, allowing nodes to be
upgraded independently and without disruption to other nodes. While a gradual
upgrade occurs, compatibility between IPv6 and IPv4 nodes becomes a requirement.
Otherwise, an IPv6 node would not be able to communicate with an IPv4 node.
Transition mechanisms allow IPv6 and IPv4 nodes to coexist together in the same
network, and make gradual upgrading possible. The transition mechanism supported
by the JUNOS Software is tunneling. Tunnels allow IPv6 packets to be encapsulated
into IPv4 headers and sent across an IPv4 infrastructure. For more information about
configuring tunnels to support IPv4-to-IPv6 transition, see the JUNOS Services Interfaces
Configuration Guide.
VRRP Properties
The Virtual Router Redundancy Protocol (VRRP) provides a much faster switchover
to a backup router when the default router fails. Using VRRP, a backup router can
take over a failed default router within a few seconds. This is done with minimum
amount of VRRP traffic and without any interactions with the hosts.
For more information on VRRP properties, see the JUNOS High Availability
Configuration Guide.
Configuring the Interface Address
You assign an address to an interface by specifying the address when configuring
the protocol family. For the
