On MikroTik devices, label management for the LDP (Label Distribution Protocol) protocol used in MPLS (Multiprotocol Label Switching) networks is generally done dynamically.

LDP is the protocol responsible for assigning and distributing labels (labels) between routers in an MPLS network. Dynamic allocation is critical to the operation of MPLS, allowing routers to establish and maintain label paths in an efficient and scalable manner.

However, MikroTik also offers flexibility in MPLS and LDP configuration, including some options that allow for more controlled label manipulations:

Static Label Bindings

Although LDP handles labels dynamically, MikroTik allows the configuration of “Static Label Bindings”. This means that an administrator can manually assign specific tags to certain routes. This option is useful in scenarios where more detailed control of the path that traffic should follow is required, or for testing and debugging purposes.

Label Filters

In MikroTik, it is also possible to configure tag filters that allow you to control which tags are accepted, rejected or modified when passing through a router. This can be used to influence the routing process or to implement specific network policies.

LDP Configuration

MikroTik devices allow you to adjust various LDP protocol parameters, such as tag lifetime, LDP session parameters, and tag distribution policies. This provides administrators with considerable ability to adjust how and when tags are assigned and used.

To configure static labels or adjust LDP behaviors on a MikroTik device, MPLS and LDP settings are usually accessed through the configuration menu in the RouterOS software, using the command line interface or available graphical tools.

It is important to note that any manual adjustments must be made carefully to avoid disrupting the normal operation of the MPLS network.
