The internet loopback 127.0.0.0

‎05-22-2019 11:42 AM
I have read that this address is the internet loopback which exists on all internet appliances. I assume. Anyway, is it necessary to set this in the lo0 of the srx?

Does anyone do this?

Seems as though it already handled this.

Any comments are welcome.

I'm not referring to 127.0.0.1

Eugene,

 

You dont need to configure that address in junos devices. The 127.0.0.0 is just a network address; actaully within that network we could find addresses like 127.0.0.1 which is configured on the SRX by default:

 

root@a13-17> show interfaces terse lo0
Interface               Admin Link Proto    Local                 Remote
lo0                     up    up
lo0.16384               up    up   inet     127.0.0.1           --> 0/0
lo0.16385               up    up   inet

 In short you dont need to configure the 127.0.0.0 for enabling any funtionalities on the SRX.
