To enable OSPFv3 on MikroTik RouterOS, which is the version of the OSPF protocol designed for IPv6 networks, you must follow a series of specific steps. OSPFv3 is configured somewhat differently than OSPFv2, which is used for IPv4.

Here is a detailed guide on how to configure OSPFv3 on a MikroTik device:

1. Access to the Router

First, make sure you have access to the MikroTik device, either through the graphical user interface (WinBox) or through the command line interface (CLI).

2. Enable OSPFv3 Package

Before you can configure OSPFv3, you need to ensure that the package routing is enabled on your system. You can check and install this package from the “System” -> “Packages” menu in WinBox or using the command in the CLI:

/system package print

If packet routing is not enabled, you must enable it and restart the router.

3. OSPFv3 configuration

Once the package is active, you can begin configuring OSPFv3:

to. Define an OSPFv3 Instance

Create a new OSPFv3 instance that will define the basic protocol configurations on your network.

/ipv6 ospf-v3 instance
add name=default-ospfv3 router-id=1.1.1.1

• name: Name of the instance.
• router-id: Unique identifier for the router within the OSPFv3 network. It must be a unique IPv4 address, even if OSPFv3 is used for IPv6.

b. Configure OSPFv3 Areas

OSPF areas divide the network into logical segments. You can configure one or more areas within the OSPFv3 instance.

/ipv6 ospf-v3 area
add instance=default-ospfv3 name=area0 area-id=0.0.0.0

• instance: The OSPFv3 instance to which this area belongs.
• name: Name of the area.
• area-id: Area identifier, usually used 0.0.0.0 for the backbone area.

c. Configure OSPFv3 Interfaces

You must assign the interfaces that will participate in OSPFv3 to the corresponding instance and area.

/ipv6 ospf-v3 interface
add interface=ether1 area=area0

• interface: Name of the network interface.
• area: OSPFv3 area to which this interface belongs.

4. Check Settings

After configuring OSPFv3, it is important to verify that the protocol is operating correctly.

/ipv6 ospf-v3 neighbor print

This command displays detected OSPFv3 neighbors, which is useful for confirming that OSPFv3 communication is working between devices.

5. Additional Settings and Optimization

You can make additional settings such as configuring authentication, timer settings, and route filtering based on your network's specific needs.

Configuring OSPFv3 in MikroTik is a comprehensive process that requires a clear understanding of how OSPF handles routing in an IPv6 network. Be sure to carefully plan your setup to maintain a stable and efficient network.
