The local MAC age over CEP interface is similar to the Layer 2 MAC age. After the local MAC delete, the MAC withdrawal route is sent to the MCT peer.
The local MAC age over CCEP interface is considered aged only if all MCT nodes age out the entry. When the MAC that ages on one of the MCT node local MDB is deleted, if the remote MDB present MAC is reprogrammed as the CCR, else the MAC is removed from the local FDB, the MAC withdrawal route is sent to MCT peer.
The remote MAC addresses that are learned through the MAC advertisement route does not age out. They can only be removed by the MAC withdraw messages from the peer.
