Adding The Interface Mtu Into Dd Packets - HPE FlexNetwork HSR6800 Configuration Manual

Configure the new MD5/HMAC-MD5 authentication key on all neighbor devices. When the local
2.
device receives packets with the new key from all neighbor devices, it exits MD5 key rollover.
Delete the old MD5/HMAC-MD5 authentication key from the local device and all its neighbors.
3.
This operation helps prevent attacks from devices that use the old key for communication and
reduces system resources and bandwidth consumption caused by key rollover.
