Group installation relies on timeouts. This is wrong.

In the file ElanInterfaceManager:

public void installEntriesForFirstInterfaceonDpn(ElanInstance elanInfo, InterfaceInfo interfaceInfo,
DpnInterfaces dpnInterfaces, boolean isFirstInterfaceInDpn, WriteTransaction tx) {
if (!isOperational(interfaceInfo))

{ return; }

// LocalBroadcast Group creation with elan-Interfaces
setupLocalBroadcastGroups(elanInfo, dpnInterfaces, interfaceInfo);
if (isFirstInterfaceInDpn) {
LOG.trace("waitTimeForSyncInstall is {}", WAIT_TIME_FOR_SYNC_INSTALL);
BigInteger dpId = interfaceInfo.getDpId();
// RemoteBroadcast Group creation
try

{ Thread.sleep(WAIT_TIME_FOR_SYNC_INSTALL); } catch (InterruptedException e1) {
LOG.warn("Error while waiting for local BC group for ELAN {} to install", elanInfo);
}
setupElanBroadcastGroups(elanInfo, dpnInterfaces, dpId);
try { Thread.sleep(WAIT_TIME_FOR_SYNC_INSTALL); }

catch (InterruptedException e1) {
LOG.warn("Error while waiting for local BC group for ELAN {} to install", elanInfo);
}
}
}
