Junos OS

hello guys need your help whether this is a correct config.

netscreen:
set route 0.0.0.0/0 interface e_if_3 gateway 8.1.QQ.XX preference 20

-------

JunOS:
set interfaces ge-1/2/0 unit 1 description to->outside_world
set interfaces ge-1/2/0 unit 1 Inside_Me inet address 5.1.QQ.XX/27

set routing-options static route 0.0.0.0/0 next-hop 8.1.QQ.XX preference 20

is it okay to specify subnet mask "/27" or it should be "/24"?

Correct subnet mask is /27, when configuring  does it needs to be set as "/24"?

Thanks for any help.

Hi JJJCR,

If the correct subnet is /27 you need to specify /27 itself.

You do not need to specify /24.

If the subnet is /30 you should specify it as /30.

Hi ssn, thanks for the clarification.

Is the configuration correct?

Thanks.

Yes JJJCR , the configuration is correct.

I am assuming that you want the prefernce of the static route to be set as 20.

Yes, i'm setting the preference to 20 because there is another route.

But if I will be having one static route, I can omit the preference?

Hello,

No it is not correct as JUNOS won't allow You to set "unit 1" without "vlan-tagging" + "vlan-id" knobs, it has to be "unit 0" then.

HTH

Thanks
