Juniper To MikroTik – OSPF Commands

Kevin Myers 1 Comment

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.

set protocols ospf area 0.0.0.0 interface ge-0/0/0.0 dead-interval 4		/routing ospf interface add dead-interval=4s hello-interval=1s interface=ether1 network-type=point-to-point

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

Juniper to MikroTik – BGP 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.  We’ll be working through several protocols over series of posts to help you quickly move between different environments. 

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 of this testing utilizing EVE-NG and the topology seen below.

set policy-options policy-statement REDIS-CONNECTED term 1 then accept
set protocols bgp group EBGP export REDIS-CONNECTED
/routing bgp network
add network=100.89.88.0/24
add network=100.89.87.0/24
add network=100.89.86.0/24
set routing-options static route 0.0.0.0/0 discard
set protocols bgp group EBGP export SEND-DEFAULT
set policy-options policy-statement SEND-DEFAULT term 1 from protocol static
set policy-options policy-statement SEND-DEFAULT term 1 from route-filter 0.0.0.0/0 exact
set policy-options policy-statement SEND-DEFAULT term 1 then accept
/routing bgp peer
add default-originate-always name=PEER-1 remote-address=172.31.254.1 remote-as=1


Examples of the commands above

This is a quick way to get a list of the peers/ASN and their status

[admin@MIKROTIK-BGP] > routing bgp peer print brief

root@JUNOS-BGP> show bgp summary

This next command will show you more information about a peer.  In this case we did not specify the peer as there is only one.  On a peering router with multiple peers it is recommended to look only at specific peer information to not be overwhelmed with irrelevant information. 

[admin@MIKROTIK-BGP] > routing bgp peer print status

root@JUNOS-BGP> show bgp neighbor

The next command allows you to see the prefixes that are sent to your peer as well as the next-hop associated with it. 

[admin@MIKROTIK-BGP] > routing bgp advertisements print peer=PEER-1

root@JUNOS-BGP> show route advertising-protocol bgp 172.31.254.2

This next one will show you what routes were received from the peer and the next-hop you will advertise. 

[admin@MIKROTIK-BGP] > ip route print where received-from=PEER-1

root@JUNOS-BGP> show route receive-protocol bgp 172.31.254.2

Here we will see the BGP prefixes that are in the routing table – both active and not.  On junOS you will see the count for hidden routes in the output but you will not see the hidden entries.  This will require the use of “show route protocol bgp hidden” to see the hidden entries.  On mikrotik you will see this type of route in the route table as inactive. 

[admin@MIKROTIK-BGP] > ip route print where bgp=yes

root@JUNOS-BGP> show route protocol bgp

Configure BGP instance, peering, and originate a default route. 

Here is a very basic BGP peering configuration to establish a peer, advertise a few routes, and originate a default route. 

Let’s look at some of the differences in the configuration. 

It’s worth noting that everything in CAPS was manually defined . 

On junOS there is no concept of the “network” command that you might see in MikroTik or Cisco.

To accomplish the same functionality in this example I used a policy-statement named REDIS-CONNECTED that matched any connected route for redistribution. 

This is then applied as an export statement into the EBGP peer group.  Likewise, there is not a construct for “default-originate”.  In order to accomplish the same functionality, we created a static route to discard and exported this to the EBGP peer.

MikroTik BGP Configuration

/routing bgp instance
set default as=2
/routing bgp network
add network=100.89.88.0/24
add network=100.89.87.0/24
add network=100.89.86.0/24
/routing bgp peer
add default-originate=always name=PEER-1 remote-address=172.31.254.1 remote-as=1

Juniper BGP Configuration

set interfaces lo0 unit 0 family inet address 100.99.98.1/24
set interfaces lo0 unit 0 family inet address 100.99.97.1/24
set interfaces lo0 unit 0 family inet address 100.99.96.1/24
set routing-options static route 0.0.0.0/0 discard
set routing-options autonomous-system 1
set protocols bgp group EBGP type external
set protocols bgp group EBGP export REDIS-CONNECTED
set protocols bgp group EBGP export SEND-DEFAULT
set protocols bgp group EBGP peer-as 2
set protocols bgp group EBGP neighbor 172.31.254.2
set policy-options policy-statement REDIS-CONNECTED term 1 from protocol direct
set policy-options policy-statement REDIS-CONNECTED term 1 then accept
set policy-options policy-statement SEND-DEFAULT term 1 from protocol static
set policy-options policy-statement SEND-DEFAULT term 1 from route-filter 0.0.0.0/0 exact
set policy-options policy-statement SEND-DEFAULT term 1 then accept

More to come

There are so many commands to consider for BGP, we probably could have added close to 100, but we decided to list the commands we use most often to start with and will be adding to the list of BGP commands as well as other like OSPF, MPLS, and VLANs in future posts.
