set interfaces em5 unit 0 family inet address 10.42.12.1/24
[edit]
ariel@R1#
set interfaces em4 unit 0 family inet address 10.42.13.1/24
[edit]
ariel@R1#

7. To Verify the Interfaces IP Addresses
ariel@R1>
show configuration interfaces
em4 {
unit 0 {
family inet {
address 10.42.13.1/24;
}
}
}
em5 {
unit 0 {
family inet {
address 10.42.12.1/24;
}
}
}
lo0 {
unit 0 {
family inet {
address 1.1.1.1/32;
}
}
}
(Note: Apply the necessary configuration on
