Replicated Cache in ehcache and spring-boot - spring-boot

Question

ehcache version 2.8.3 is being used in spring-boot.
The server to be tested is server A and server B based on linux
There are three kinds of cache
Below is the ehcache.xml configuration.
<ehcache>
<diskStore path="java.io.tmpdir" />
<cacheManagerPeerProviderFactory class="net.sf.ehcache.distribution.RMICacheManagerPeerProviderFactory"
properties="peerDiscovery=automatic, multicastGroupAddress=230.0.0.1, multicastGroupPort=40001,
timeToLive=1 ,replicatePuts=true,replicatePutsViaCopy=true ,replicateUpdates=true ,replicateUpdatesViaCopy=false,
replicateRemovals=true ,replicateAsynchronously=false"/>
<cacheManagerPeerListenerFactory class="net.sf.ehcache.distribution.RMICacheManagerPeerListenerFactory"
properties="socketTimeoutMillis=2000, port=40001"/>
<cache name="aCache"
maxElementsInMemory="0"
eternal="true"
timeToIdleSeconds="0"
timeToLiveSeconds="0"
overflowToDisk="false">
<cacheEventListenerFactory class="net.sf.ehcache.distribution.RMICacheReplicatorFactory"/>
<bootstrapCacheLoaderFactory
class="net.sf.ehcache.distribution.RMIBootstrapCacheLoaderFactory"
properties="bootstrapAsynchronously=true"
propertySeparator="," />
<!-- <cacheEventListenerFactory class="net.sf.ehcache.distribution.RMICacheReplicatorFactory"
properties="replicateAsynchronously=true, replicatePuts=true, replicateUpdates=true,
replicateUpdatesViaCopy=false, replicateRemovals=true"/> -->
</cache>
<cache name="bCache"
maxElementsInMemory="0"
eternal="true"
timeToIdleSeconds="0"
timeToLiveSeconds="0"
overflowToDisk="false">
<cacheEventListenerFactory class="net.sf.ehcache.distribution.RMICacheReplicatorFactory"/>
<bootstrapCacheLoaderFactory
class="net.sf.ehcache.distribution.RMIBootstrapCacheLoaderFactory"
properties="bootstrapAsynchronously=true"
propertySeparator="," />
</cache>
<cache name="cCache"
maxElementsInMemory="0"
eternal="true"
timeToIdleSeconds="0"
timeToLiveSeconds="0"
overflowToDisk="false">
<cacheEventListenerFactory class="net.sf.ehcache.distribution.RMICacheReplicatorFactory"/>
<bootstrapCacheLoaderFactory
class="net.sf.ehcache.distribution.RMIBootstrapCacheLoaderFactory"
properties="bootstrapAsynchronously=true"
propertySeparator="," />
</cache>
</ehcache>
Ehcache.xml on Server A and Server B are entered with the same settings.
When I add a cache on server A, I want to see the a cache added on server B
Only the following logs would be displayed, but Server B could not check the added cache.
[Multicast Heartbeat Receiver Thread] DEBUG n.s.e.d.MulticastKeepaliveHeartbeatReceiver - rmiUrls received //192.168.10.20:40001/aCache|//192.168.10.20:40001/bCache|//192.168.10.20:40001/cCache
If you know how, please let me know.
