== Situation und beobachtetes Verhalten ===
  * gluon-mesh-prefix ist: 
  * gluon-prefix6 ist:
  * radvd, l3roamd, babeld laufen
  * Der client erhält eine ipv6-Adresse im gluon.mesh_prefix
  * Der Client kann den Node pingen
  * Der Client kann einen anderen über Mesh verbundenen Node nicht erreichen weil keine Rückrouten existieren
  * die ipv6-routingtabelle 11 (die l3roamd-Ausgabe-Tabelle) wird mit einer unreachable-route zu der zum Client zugehörigen fec-Adressen (hart in l3roamd kodierte Adressen) befüllt.
  * logread zeigt: 
    [  382.770000] eth0: link up (1000Mbps/Full duplex)
    [  382.770000] br-client: port 1(eth0) entered forwarding state

    error: netlink error: Resource temporarily unavailable
    error: netlink error: Resource temporarily unavailable
