How to Configure Static Route on a Juniper Switch | vQFX | EVE-NG

 Topology:

To make VPC5 communicate with VPC6, lets add static route on both the Switches. VPC5 is in vlan10 and VPC6 is in vlan20.

VPC5

IP: 172.17.10.1/24

GW: 172.17.10.100

VPC6

IP: 172.17.20.1/24

GW: 172.17.20.100

irb.10 = 172.17.10.100

irb.20 = 172.17.20.100

Refer previous blogs in relation to vlan creation and irb interface configuration.

vlan configuration: https://aaqiltech.blogspot.com/2023/02/creating-vlans-on-juniper-switch-vqfx.html

root@vqfx-re# show 

HR {

    vlan-id 10;

    l3-interface irb.10;

}

default {

    vlan-id 1;

}

{master:0}[edit vlans]

irb interface configuration: https://aaqiltech.blogspot.com/2023/04/creating-irb-interfaces-vqfx-eve-ng.html

root@vqfx-re# show 

unit 10 {

    family inet {

        address 172.17.10.100/24;

    }

}

{master:0}[edit interfaces irb]

Let's assign IP address for p2p interfaces on both switches

root@vqfx-re# set interfaces xe-0/0/10 unit 0 family inet address 1.1.1.1/24

root@vqfx-re# set interfaces xe-0/0/10 unit 0 family inet address 1.1.1.2/24
root@vqfx-re# show 
unit 0 {
    family inet {
        address 1.1.1.1/24;
    }
}
{master:0}[edit interfaces xe-0/0/10]

Lets configure static route on both switches

root@vqfx-re# set routing-options static route 172.17.20.0/24 next-hop 1.1.1.2

root@vqfx-re# set routing-options static route 172.17.10.0/24 next-hop 1.1.1.1

root@vqfx-re# show 

static {

    route 172.17.20.0/24 next-hop 1.1.1.2;

}

{master:0}[edit routing-options]

Verify the the static route configured

root@vqfx-re> show route 

inet.0: 7 destinations, 7 routes (7 active, 0 holddown, 0 hidden)

+ = Active Route, - = Last Active, * = Both

172.17.20.0/24     *[Static/5] 00:11:45

                    >  to 1.1.1.2 via xe-0/0/10.0

Now both the PCs should be able to communicate with each other.
