Juniper To MikroTik – OSPF 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 portion of the series we will be covering Open Shortest Path First, OSPF, version 2 which is a popular interior gateway protocol (IGP).

You can find the first article of the series Juniper to Mikrotik – BGP Commands here.

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 all testing on EVE-NG utilizing the topology seen below.

Examples of the commands above

This first command will show you all of the routers you have an OSPF neighbor adjacency with.

[admin@MIKROTIK-OSPF] > routing ospf neighbor print

root@JUNOS-OSPF> show ospf neighbor

This next command lists all of the interface enabled for OSPF as well as some basic information such as cost, priority, and network type. Juniper displays slightly different information such as area, DR info, and number of neighbors. Juniper does not have the concept of a network statement so interfaces explicitly configured for OSPF will appear here. You can optionally add the detail command on JunOS for more information.

[admin@MIKROTIK-OSPF] > routing ospf interface print

root@JUNOS-OSPF> show ospf interface

This command will list all of the details regarding the OSPF instances running on the router.

[admin@MIKROTIK-OSPF] > routing ospf instance print

root@JUNOS-OSPF> show ospf overview brief

This command lists all of the OSPF LSAs as well as some details about them.

[admin@MIKROTIK-OSPF] > routing ospf lsa print

root@JUNOS-OSPF> show ospf database

This next command will show all of the OSPF routes in the routing table.

[admin@MIKROTIK-OSPF] > ip route print where ospf=yes

root@JUNOS-OSPF> show route protocol ospf

This next set of commands will show you the area-border-routers or autonomous-system-boundary routers. We injected a connected route into OSPF to generate a type-5 LSA for an external route.

[admin@MIKROTIK-OSPF] > routing ospf area-border-router print

[admin@MIKROTIK-OSPF] > routing ospf as-border-router print

root@JUNOS-OSPF> show ospf route abr

root@JUNOS-OSPF> show ospf route asbr
