Operational Behavior of Interfaces when the Same IPv4 Address is Assigned to
Them
You can configure the same IPv4 address on multiple physical interfaces. When you
assign the same IPv4 address to multiple physical interfaces, the operational behavior
of those interfaces differs, depending on whether they are implicitly or explicitly
point-to-point .
NOTE: By default, all interfaces are assumed to be point-to-point (PPP)
interfaces. For all interfaces except aggregated Ethernet, Fast Ethernet, and
Gigabit Ethernet, you can explicitly configure an interface to be a
point-to-point connection.
The following examples show the sample configuration of assigning the same IPv4
address to implicitly and explicilty point-to-point interfaces, and their corresponding
show interfaces terse command outputs to see their operational status.
Configuring same IPv4 address on implicitly PPP interfaces:
[edit]
user@host# show
ge-0/1/0 {
unit 0 {
family inet {
address 200.1.1.1/24;
}
}
}
ge-3/0/1 {
unit 0 {
family inet {
address 200.1.1.1/24;
}
}
}
The sample output shown below for the above configuration reveals that only
ge-0/1/0.0 was assigned the same IPv4 address 200.1.1.1/24 and its link state was up,
while ge-3/0/1.0 was not assigned the IPv4 address, though its link state was up,
which means that it will be operational only when it gets a unique IPv4 address other
than 200.1.1.1/24.
