Our goal is to configure routing instances on all devices and provide routing between all instances with ospf protocol. Configure routing instances on SRX1: We will be using a tagged interface ge-0/0/1 where vlan 10 is for vr10.10 routing instance and vlan 20 is for vr20.20: set interfaces ge-0/0/1 vlan-tagging set interfaces ge-0/0/1 unit 10 vlan-id 10 set interfaces ge-0/0/1 unit 10 family inet address 172.16.10.1/24 set interfaces ge-0/0/1 unit 20 vlan-id 20 set interfaces ge-0/0/1 unit 20 family inet address 172.16.20.1/24 Now create routing instances and assign interfaces to them: set routing-instances vr10.10 instance-type virtual-router set routing-instances vr10.10 interface ge-0/0/1.10 set routing-instances vr20.20 instance-type virtual-router set routing-instances vr20.20 interface ge-0/0/1.20 Configure rib-groups to import routes from one routing instance to another (Another alternative is to configure policy-options for importing): set routing-instances vr10.10 routing-opti
