GetVPN GMs not finding KS via alternative interfaces.
The registration with the KS is ok during normal operation but when a topology change occurs, the GM is unable to start GDOI because the interface is down, for instance. The crypto map is applied to a second interface and we have reachability from loopback to loopback. The message I get is
%CRYPTO-4-GM_REGSTER_IF_DOWN: Can't start GDOI registeration as interface FastEthernet0/1 is down
If I remove the crypto map from the first interface, the whole process starts and I get registered right away. It does not run while the crypto map is on both interfaces.
