MC-LAG: Configuration synchronization for multichassis link aggregation groups

Multichassis link aggregation group (MC-LAG) configuration synchronization enables you to easily propagate, synchronize, and commit configurations from one MC-LAG peer to another. Log in to either peer to manage both, and use configuration groups to simplify the configuration process. You can create one configuration group each for the local peer and the remote peer, and a global configuration common to both peers. Create conditional groups to specify when peer configurations are synchronized. Enable peers-synchronize at the [edit system commit] hierarchy to synchronize configurations and commits across peers by default. NETCONF over SSH provides a secure connection between peers; Secure Copy Protocol (SCP) copies configurations securely between them.
