Let’s check the connectivity by executing a ping. On R2, I am using configuration statement “set logical-systems R1 interfaces lt-1/2/0 unit 2 peer-unit 1” which tells the router to connect to lt-1/2/0 interface unit#1 in whatever logical-system it is.On R1, I am using configuration statement “set logical-systems R1 interfaces lt-1/2/0 unit 1 peer-unit 2” which tells the router to connect to lt-1/2/0 interface unit#2 in whatever logical-system it is.In the above configuration snippet, check out the peer-unit configuration under interface configuration hierarchy. Set logical-systems R2 interfaces lt-1/2/0 unit 2 family mpls Set logical-systems R2 interfaces lt-1/2/0 unit 2 peer-unit 1 set logical-systems R2 interfaces lt-1/2/0 unit 2 family inet address 172.16.12.2/24 Set logical-systems R2 interfaces lt-1/2/0 unit 2 encapsulation ethernet Set logical-systems R2 interfaces lt-1/2/0 unit 2 description R1.R2 Set logical-systems R1 interfaces lt-1/2/0 unit 1 peer-unit 2 set logical-systems R1 interfaces lt-1/2/0 unit 1 family inet address 172.16.12.1/24įor R2, I am creating sub-interface using unit 2 which will be part of logical-system R2 and assigning it IP address. Set logical-systems R1 interfaces lt-1/2/0 unit 1 encapsulation ethernet
Set logical-systems R1 interfaces lt-1/2/0 unit 1 description R1.R2 Now let’s make a connection between R1 and R2:įor R1, I am creating sub interface using unit 1 which will be part of logical-system R1 and assigning it IP address. I can see the 2 logical routers are created in following command: I will have to create 2 logical routers for our topology: To create logical router execute following command by entering configuration mode:
So with that said, let’s start working on creating logical-routers and connections between them using the lt interface. Great – I have lt-1/2/0 interface on my router, so I can use that single interface to interconnect all the logical routers. To check that, execute following command, and look for interface names start with “lt-“. Configuration commands for configuring any feature or any protocols are same as if you configure it on a physical router.įirst of all, let’s start by verifying if the router has an LT interface or not. You can build up to 15 logical routers on one physical router, and you can connect them using logical tunnel (lt) interfaces or by making physical connections. In this post, I might say “logical-routers” or “logical-systems.” Both refer to the same entity. To demonstrate Junos logical routers, I will start with R1 and R2 logical routers.

I mostly deal with M, T and MX series routers, so the test scenario that I will be covering is related to those routers. On a Junos router, you can build logical routers on physical router.
To answer the above questions, I am writing this post.
This artical covers the physical router with many logical systems connected via physical or logical tunnel interface. In virtualization word, you have other options of vMX device you can spin up on servers or laptops.

Want to start learning Junos? Want to start working on a Juniper certification? Is there a simulator available? What if you have only one or two physical routers – how can you get the most out of them?
