SRX

If I have statically assigned IP from my ISP that I am going to assign to ge-0/0/6 unit 0, do I need to use this option?

And can someone please explain the difference between these two?

set interfaces ge-0/0/6 unit 0 family inet dhcp update-server

set interfaces ge-0/0/6 unit 0 family inet dhcp

Thank you.

What option do you mean you have to configure ?

Sorry, by option I mean:

set interfaces ge-0/0/6 unit 0 family inet dhcp update-server

or

set interfaces ge-0/0/6 unit 0 family inet dhcp

I am assigning IP from my ISP - static IP address to: ge-0/0/6 unit 0 and I already have VLANs configured with DHCP pools, too.

I don't think I need to use: dhcp update-server or inet dhcp in my case.

Am I right?

When do we use it in Juniper?

And what is the difference between them?

I have seen some examples, but it is still unclear to me.

Thank you.

We use the update-server option to pass DNS, domain-name, etc.. info that we learn from our ISP to pass to the DHCP clients being served by SRX.

We use this in our setup:

ge-0/0/0 {
    unit 0 {
        family inet {
            dhcp-client {
                update-server;
            }
        }
    }
}

If the SRX is not acting as a DHCP server, then the 'update-server' option doesn't do anything.

Hope this helps.

If you have a static config from your ISP then you can configure

set interfaces ge-0/0/6 unit 0 family inet address x.x.x.x/subnetmask

and add a default route

set routing options static route 0.0.0.0/0 next-hop <gw-ip>

Excellent!

Thank you both, Marc and Sam!
