MLAG and MC-LAG (multi-chassis link aggregation)
Two switches presenting themselves as one logical switch to a downstream device, so a server or switch can be connected to both with one bundled link and survive the loss of either.
In REAP
Peer-link state, consistency parameters and orphan ports are part of the resilience checks on redundant pairs.
