Hello,

I have a problem with configuring multiple interfaces with separate gateways, can someone maybe help me?

Interface ge0/0/0 - network 1 - ip 192.168.100.1

Interface ge0/0/1 - network 2 - ip 192.168.200.1

Interface ge0/0/2 - network 3 - ip 192.168.0.1

Network 1 should have 192.168.100.254 as an gateway
Network 2 should have 192.168.200.254 as an gateway

Network 3 should have 192.168.0.254 as an gateway

I really can't find a way to do this.

Thanks.

Hi Chrizzieej ,

Do you want to configure 3 default routes with 3 different default gateways?

if yes ,you need 2 routing instances for each interfaces interfaces.

For Network 1 should have 192.168.100.254 as an gateway

set routing-options static route 0/0 next-hop 192.168.100.254

For network2  

set routing-instances test1 interface ge-0/0/1

set routing0-instances test1 routing-options static route 0/0 next-hop 192.168.200.254

For  network 3:

set routing-instances test2 interface ge-0/0/2

set routing0-instances test2 routing-options static route 0/0 next-hop 192.168.0.254

Then if you need communication between each routing instances , then you need share the routes using import and export of routes as per this KB :

Assign each interfaces to security zones and configure security policies to allow or deny traffic.

Hope this helps....

This doesn't work, it says that the interface has to be in the same subnet as the other interfaces.

Sorry my mistake, it works
