In this lesson, I will show you how you can add or change a domain-name on the Juniper router. This is sometimes required by your company that the Juniper belongs to the domain of that company.
Let’s move forward – first let’s see if the router has already a domain name set on it:
root@Juniper# show
## Last changed: 2024-02-06 14:31:12 UTC
version 12.1X44.5;
system {
host-name Juniper;
root-authentication {
encrypted-password “$1$qFS2OEKp$gXfJyeQG9MAAQIsdwk5Vg0”; ## SECRET-DATA
}
name-server {
208.67.222.222;
208.67.220.220;
}
services {
ssh {
protocol-version v2;
}
telnet;
xnm-clear-text;
web-management {
http {
interface vlan.0;
}
https {
system-generated-certificate;
—(more)—
Normally, if there is a domain name it will be shown on the 1st page of the “show” command, meaning that there is no domain name on this router.
Let’s add one, I will choose Juniper.local.
root@Juniper# set system domain-name Juniper.local
[edit]
root@Juniper# commit
This way you can add the domain name.
Finally, let’s issue a show to see if the domain name that we have added is shown now:
root@Juniper# show
## Last changed: 2024-02-06 14:39:51 UTC
version 12.1X44.5;
system {
host-name Juniper;
domain-name Juniper.local;
Indeed, it is shown now 😊
That’s all what you need to know about the domain name, see you in the upcoming lessons.
