Hi - Yes it took a while. It has stopped working. When I issued the "clear crypto isakmp" command it stopped working. So now I can try to work out how to get the multicast through the ASA.

Reduce the rekey restransmit time to minimum and run debugs on the GMs to see if you are receiving rekeys once they are retransmitted. ( alternatively, you can change the ACL to force a rekey). But remember, clearing GDOI on GMs or any change on GMs will cause re-registration which will work fine. (Its unicast and in opposite direction) With ASA in between multicast rekey should NOT work. But lets first make sure its not working and then we can implement the workarounds later.

I put an ASA 5510 between the KS and the 2 GM's. I set the keying as unicast which worked fine. I changed the keying to multicast and it is still working?? Shouldn't I have to do something on the ASA to pass multicast traffic for GETVPN. I vaguely remember Tyson doing this in the bootcamp to make it work so I am a bit confused. Can anyone please clarify what we need to do if a getvpn using multicast keys traverses an ASA or another router?
