JunOS basic configuration

Testing

To check if everything work, let’s configure 2 Olives:

root@%cli
root>edit
[edit]
root#

[edit]
root#set system root-authentication plain-text-password
New password:
Retype new password:

[edit]
root#set interfaces em0 unit 0 family inet address 10.0.0.1/8
[edit]
root#commit
commit complete

Configure the other device using the same commands but with another IP address (e.g. 10.0.0.2/8) and ping.

root#exit
Exiting configuration mode
root> ping 10.0.0.2
PING 10.0.0.2 (10.0.0.2): 56 data bytes

64 bytes from 10.0.0.2: icmp_seq=0 ttl=64 time=9.771 ms
64 bytes from 10.0.0.2: icmp_seq=1 ttl=64 time=0.614 ms
64 bytes from 10.0.0.2: icmp_seq=2 ttl=64 time=0.693 ms
64 bytes from 10.0.0.2: icmp_seq=3 ttl=64 time=0.630 ms

Additionally, configure OSPF (or any other multicast based protocol) to test if your routers can talk to each other using multicast packets. Again, type those commands on both routers:

root# set protocols ospf area 0 interface em0

[edit]
root# commit
commit complete

[edit]
root# exit
Exiting configuration mode

Then monitor the traffic from one of the router, you should see some multicast traffic (from/to 224.0.0.5):

root> monitor traffic interface em0

02:30:30.973748 Out IP 10.0.0.1 > 224.0.0.5: OSPFv2, Hello, length 48
02:30:31.007675  In IP 10.0.0.2 > 224.0.0.5: OSPFv2, Hello, length 48

Is everything working? yes? then you are successfully running JunOS! Happy networking
