In this way, the forwarding table entries of each device in the fabric can be consistent. Even if the master
fails, other devices can use the forwarding table synchronized from the master to perform layer 3
forwarding, thus ensuring the accuracy of forwarding path. After re-electing the master, the fabric will
restart routing update.
DLA
As a new link aggregation mode, DLA can improve fault tolerance and redundancy backup of user
networks.
Link aggregation enables you to configure ports on the same device as an aggregation port group,
avoiding network interruptions resulted from single port failure. Based on link aggregation, DLA
provides a more reliable solution, with which you can select ports on different devices to form an
aggregation port group. In this way, single port failure can be avoided and network reliability can be
greatly improved, because the fabric can communicate with the destination network through ports on
other devices in case a single device fails.
