Configuring routing in Juniper router

  • 772

I have a Juniper SRX220 (junos) router where I have configured vlan.1 and vlan.2 with IP 10.0.1.1/24 and 10.0.2.1/24. Now I want to route between these networks. How do I configure that in Junos? I can't figure that out from the manual and it does not work out of the box.

    Because this is an SRX, there are a number of requirements here.

    Step 1:

    Define VLANS (think layer 2)

    set vlans vlan1 description desktops vlan-id 1 l3-interface vlan.1

set vlans vlan2 description servers vlan-id 2 l3-interface vlan.2

    Step 2:

    Define L3 interfaces bound to those vlans...

    set interfaces vlan unit 1 family inet address 10.0.1.1/24

set interfaces vlan unit 2 family inet addresses 10.0.2.1/24

    Step 3:

    Place those L3 interfaces into a zone

    set security zones security-zone trust interfaces vlan.1

set security zones security-zone trust interfaces vlan.2

    Step 4:

    Since this is an SRX, you must create a policy permitting intra-zone traffic

    set security policies from-zone trust to-zone trust policy trust-to-trust match source-address any destination-address any application any then permit

    Step 5:

    Set physical interfaces onto that VLAN

    set interfaces ge-0/0/0 unit 0 family ethernet switching port-mode access vlan members vlan1

set interfaces ge-0/0/1 unit 0 family ethernet switching port-mode access vlan members vlan2

    Step 6:

    Plug devices in. Once any interface assigned to that VLAN is physically up, the VLAN interface for that VLAN will come up.
