already responded to this. Ill look for his e-mail

Asa will not pass multicast in a multiconext mode. GRE tunnel will be needed 
between the routers to handle the multicast rekeying if needed.

Then it matches to what Cisco guide says about "address ipv4 x.x.x.x". You'd 
need it only for unicast rekeying to specify the source of unicasts. Since you 
used multicast your key server ID was showing 0.0.0.0

Interesting fact with the ASA passing multicasts. Is KS on the outside of ASA 
or inside ?

Subject: [OSL | CCIE_Security] Rekey address










What is the significance of the 'address ipv4 x.x.x.x' in the gdoi group 
configuration.  I was trying out a multicast rekey setup with the following 
rekey acl - access-list 150 permit udp any
 eq 848 host 239.0.1.2 eq 848.  And i didnt have the local server address 
configured.  So the Key server ID was displayed as 0.0.0.0, and everything 
worked.



So i was wondering when you really need the KS address configured?



And the traffic between the KS and the GM travels through an ASA context , and 
i havent done any kind of multicast configs on it. Still, the GM's receive the 
rekey requests. How does that work?
