Juniper ACX2000 Configuration Guide

interface, we recommend that you configure one to be the primary address to ensure
that it is selected for use with unnumbered interfaces. By default, the primary address is
used as the source address when packets originate from the interface.
For more information about unnumbered interfaces, see Configuring an Unnumbered
Interface. For more information about primary addresses, see Configuring the Interface
Address.
On the router, you can configure one physical loopback interface, lo0, and one or more
addresses on the interface.
1. To configure the physical loopback interface, include the following statements at the
[edit interfaces] hierarchy level:
[edit interfaces]
lo0 {
unit 0 {
family inet {
address loopback-address;
address <loopback-address2>;
...
}
family inet6 {
address loopback-address;
}
}
}
Example: Configuring Two Addresses on the Loopback Interface with Host Routes
To configure two addresses on the loopback interface with host routes:
[edit]
user@host# edit interfaces lo0 unit 0 family inet
[edit interfaces lo0 unit 0 family inet]
user@host# set address 172.16.0.1
[edit interfaces lo0 unit 0 family inet]
user@host# set address 10.0.0.1
[edit interfaces lo0 unit 0 family inet]
user@host# top
[edit]
user@host# show
interfaces {
lo0 {
unit 0 {
family inet {
10.0.0.1;
127.0.0.1;
172.16.0.1;
}
}
}
}
