MAC address deletion

The following rules are defined for MAC address deletion. Note that every deletion triggers the MAC resolution algorithm and reprograms the MAC entry if required.

• If the CEP interface is down, MAC addresses are deleted locally and individual MAC deletion messages are sent to the peer.
• If the CCEP local port is down and the remote CCEP is down, MAC addresses are deleted locally and the ESI withdraw message is sent to the MCT peer instead of sending individual MAC delete messages.
• If the CCEP local port is down and the remote CCEP is up, all local MAC addresses are moved to point to the remote MCT peer including the static MAC addresses associated with the CCEP.
• When the client entry is undeployed, all MAC addresses are deleted locally, and the ESI withdraw message is sent to the MCT peer to delete all associated client MAC addresses.
