No neighbors with OSPF
Posted: Wed Apr 03, 2024 4:29 pm
Hello everyone,
This might sounds like a really basic problem but I'm struggling on this for two days.
I'm trying to build a simple OSPF configuration with RB3011 on OS 7.12.1, I have 3 routers with this topology:
PTR(ether6) -- CMC(ether6)
PTR(ether7) -- HOP(ether6)
CMC(ether7) -- HOP(ether7)
No matter which doc or tuto I'm following, I don't see any neighbors with the command `/routing/ospf/neighbor/print` even if my configurations looks god (for me?).
I provide you the conf of one router since it's quite the same for each router. Each router have two LAN like this (100, 101, 102, 103, 104 and 105) in 255.255.255.0 on ports ether8 and ether9.
CMC conf:
Each router is capable of pinging the direct port to which it is connected.
In the log I can the different configuration I've made but nothing related to some OSPF exchange.
The final objective is to be able to ping each interface from any router (I mean, such as OSPF do...) and is a link break still be able to communicate (such as OSPF... you get what I mean).
If any of you have an idea of why my different seams to be isolated, it would be really good to help me.
I've tried this doc: https://wiki.mikrotik.com/wiki/Manual:OSPF-examples and this one: https://help.mikrotik.com/docs/display/ROS/OSPF
Tried to take infos there: https://www.uni-koeln.de/~pbogusze/post ... ation.html (not good OS version)
