When learning how to use OSPF with MikroTik, it can sometimes be difficult to understand how the different LSA types flow between areas.

In MikroTik’s OSPF documentation they briefly cover the LSA for OSPFv2 but don’t have OSPFv3 listed yet.

To better illustrate how the LSAs work, I created these graphical overviews for OSPFv2 and OSPFv3. When troubleshooting OSPF, it’s very helpful to understand which LSAs you should see in an area and how IPv4 and IPv6 differ.

Hope you find these helpful!

When troubleshooting OSPF in MikroTik, it’s often helpful to look at the LSAs to determine the root cause of an issue.

However, MikroTik’s LSA names don’t always match up to the language used in RFCs and other resources when trying to verify the behavior of an LSA is working as intended. This can make troubleshooting difficult.

These cheat sheets match up the lsa description for OSPFv2 and OSPFv3 in RouterOSv7 with the common LSA Type and number reference.
