WLC Tunnel und IPV6

[maiki]

Hallo Forum,

ich habe einen WLC-4006+ und mehrere L-460agn AP im Einsatz. Läuft alles unter LCOS 9.20RU4.

Nun meine Frage. ich habe am WLC IPV6 eingerichet. Kabelgebunden am WLC funktioniert alles wie es soll.
Fürs WLAN habe ich dieses logische Netz via WLC-Tunnel an weitere AP´s verteilt. Via WLAN bekomme ich IPV6
leider nicht zum laufen. Kann es sein, daß durch den WLC-Tunnel keine IPV6 Pakete geleitet werden ?

Grüße

Maik

Nachtrag:

ich habe einige Traces laufen lassen. Grundsätzlich gehen IPV6 Pakete durch den WLC-Tunnel. Allerdings bleiben die IPV6 RA Pakete (router-advertising) auf der Strecke. Sprich ich sehe diese im WLC-Tunnel Trace am WLC aber am Access Point kommen die Pakete nicht an. Ich werde dies morgen weiter untersuchen.

weiterer Nachtrag:

der Trace am Access Point bei einem IPV6 Ping ergibt folgendes:

Hier scheint der Access Point das IPV6 Paket zu verwerfen, weil es nicht dem WLC-Tunnel-2 zugeordnet wird.


Ein Trace am WLC beim IPV6 Ping ergibt folgendes:

Ich bin nun ein wenig ratlos ?
