MAC Database Update over cluster control protocol

NOTE
Every MAC entry deletion triggers the resolution algorithm if the deleted MAC entry is installed in the
FDB. If the deleted MAC entry is installed in the MDB, only the MDB will be updated.
MAC entry movement
When the MAC entries move from the CEP to the CCEP or from the CCEP to the CEP, the MAC entry
movement happens normally on the local node and deletes all the other MDBs from the peer to
create a new local MDB.
Flooding support on VLANs
On the BigIron RX devices, the hardware flooding features such as unknown-unicast flooding,
multicast flooding, and VLAN CPU protection are not supported on the cluster VLANs.
