Simplest OSPF network not working with v7.1

Mon Dec 20, 2021 10:09 pm

I did the following simple network
ospf.png


Router R1:
Code: Select all
/system identity set name=R1
/routing id
add disabled=no id=0.0.0.2 name=ospf select-dynamic-id=""
/routing ospf instance
add name=ospf-instance out-filter-chain=ospf_out redistribute=\
    connected,static,ospf router-id=ospf
/routing ospf area
add instance=ospf-instance name=backbone
/ipv6 settings
set disable-ipv6=yes
/ip address
add address=192.168.100.251/24 interface=ether1 network=192.168.100.0
add address=192.168.101.254/24 interface=ether2 network=192.168.101.0
/routing filter rule
add chain=ospf_out disabled=no rule=accept
/routing ospf interface-template
add area=backbone interfaces=ether1 networks=192.168.100.0/24

Router R2:
Code: Select all
/system identity set name=R2
/routing id
add disabled=no id=0.0.0.2 name=ospf select-dynamic-id=""
/routing ospf instance
add name=ospf-instance out-filter-chain=ospf_out redistribute=\
    connected,static,ospf router-id=ospf
/routing ospf area
add instance=ospf-instance name=backbone
/ipv6 settings
set disable-ipv6=yes
/ip address
add address=192.168.100.252/24 interface=ether1 network=192.168.100.0
add address=192.168.102.254/24 interface=ether2 network=192.168.102.0
/routing filter rule
add chain=ospf_out disabled=no rule=accept
/routing ospf interface-template
add area=backbone interfaces=ether1 networks=192.168.100.0/24

Router R3:
Code: Select all
/system identity set name=R3
/routing id
add disabled=no id=0.0.0.3 name=ospf select-dynamic-id=""
/routing ospf instance
add name=ospf-instance out-filter-chain=ospf_out redistribute=\
    connected,static,ospf router-id=ospf
/routing ospf area
add instance=ospf-instance name=backbone
/ipv6 settings
set disable-ipv6=yes
/ip address
add address=192.168.100.253/24 interface=ether1 network=192.168.100.0
add address=192.168.103.254/24 interface=ether2 network=192.168.103.0
/routing filter rule
add chain=ospf_out disabled=no rule=accept
/routing ospf interface-template
add area=backbone interfaces=ether1 networks=192.168.100.0/24

Simple. But in IP > Routes I don't find any OSPF routes. Where is my mistake?
Thanks for your support.

You missed the networks you want to publish. In R1:
Code: Select all
add area=backbone networks=192.168.101.0/24
And so on...

add area=backbone networks=192.168.101.0/24
And so on...

Added in R1 (and so on):
Code: Select all
/routing ospf interface-template
add area=backbone networks=192.168.101.0/24 passive
add area=backbone networks=192.168.100.0/24
(with or without passive)

But there aren't OSPF routes.

Well, it cost me a lot to see that both R1 and R2 has the same Router-ID: 0.0.0.2. And no, there is no need to publish 192.168.10x.0/24 as you have selected 'redistribute connected' in your instance

Why mikrotik change OSPF configuration syntax in so radical way?
I have no intention do upgrade core routers to 7.x even if I wish to do so.
Now routing filters working something as scripting and that decision is awful.

Thanks, but no thanks. I will use existing 6.49 or secondhand (refurbished) cisco routers.
This, what mikrotik done is absolutely not allowed in 21. century.

Yes, I confirm that. It's a GNS3 problem: the switch (nor the links?) cut-off DD frame.
The same configuration in a real environment it's working fine. The same problem occurs using ZTE-ONU to connect Mikrotik RouterOS.
Thanks a lot for you tests.

Besta regards.

Can I contact in PM for this? I just want to ask what kind of network card is set in the mikrotik configuration in gns3.

I use X86 architecture with e1000 network card. This way I can test performance, queues... Also I use CHR with virtio when I don't mind about 1Mbps limit

I use gns3 gui and server locally installed on my laptop: i don't use Gns3 VM

You can get to me using my username at Gmail or DM with Tweeter
