Good :)

that would be the equivalent of the following configuration file:

[global]
    plugin    dlep_router
    plugin_path    /opt/git-root/oonf/build

[dlep_router]
    discovery_mc_v4    224.0.0.110
    discovery_port        270
    discovery_bindto     0.0.0.0/0


Normally you should attach the DLEP discovery to a single interface
which you use to communicate with the DLEP radio. Otherwise you will
have trouble to interpret the DLEP data because you don't know for
which interface they are.

That is the DLEP-router trying to discover the DLEP-radio.
