Juniper to Mikrotik – MPLS Commands

About the Juniper to MikroTik series

In the world of network engineering, learning a new syntax for a NOS can be daunting if you need a specific config quickly.  Juniper is a popular option for service providers/data centers and is widely deployed across the world. 

This is a continuation of the Rosetta stone for network operating systems series.  In this article we will be covering multi-protocol label switching (MPLS) using label distribution protocol (LDP). We are sticking with LDP as MikroTik does not have wide support for RSVP-TE.

You can find the first two articles of the series here:

Juniper to MikroTik – BGP commands

Juniper to MikroTik – OSPF commands

While many commands have almost the exact same information, others are as close as possible.  Since there isn’t always an exact match, sometimes you may have to run two or three commands to get the information needed. 

Using EVE-NG for testing

We conducted utilized EVE-NG for all of the testing with the topology seen below.

Examples of the commands above

This first command will show you some basic information about your MPLS LDP neighbors. On juniper you can add the keyword detail to the end for additional information on the neighbors.

[admin@MikroTik-R3] > mpls ldp neighbor print

root@JUNOS-R2> show ldp neighbor

This command will list all of the interfaces that are currently enabled for LDP.

[admin@MikroTik-R3] > mpls ldp interface print

root@JUNOS-R2> show ldp interface

Use this command to display the MPLS forwarding table which shows what labels are assigned, the interface used and the next-hop. It will also tell you the action taken such as pop, swap, or push.

[admin@MikroTik-R3] > mpls forwarding-table print

root@JUNOS-R2> show route forwarding-table family mpls

The next two commands will be combined since juniper only has one command to be equivalent to mikrotiks output. This is will show the advertised and received labels for all of the prefixes known to LDP as well as the label associated with it and where it was learned from. On JunOS you will notice label 3. This is juiper’s method to signal implicit null and request label popping by the downstream router.

[admin@MikroTik-R3] > mpls remote-bindings print

[admin@MikroTik-R3] > mpls local-bindings print

root@JUNOS-R2> show ldp database

This last command will show the label ranges and what they are used for.

[admin@MikroTik-R3] > mpls print

root@JUNOS-R2> show mpls label usage
