What is the functionality of redundant interfaces (reth) in a chassis cluster?
A.
reth interfaces are used only for VRRP.
B.
reth interfaces are the same as physical interfaces.
C.
reth interfaces are pseudo-interfaces that are considered the parent interface for two physical interfaces.
D.
Each cluster member has a reth interface that can be used to share session state information with the other cluster members.
A redundant Ethernet interface is a pseudointerface that manages two “child” physical interfaces, one on each node of the cluster. Configuration parameters set for a redundant Ethernet interface are inherited by its child interfaces. A redundant Ethernet interface allows the chassis cluster to share one IP address across two links. When a redundancy group that the redundant Ethernet interface belongs to fails over, its redundant Ethernet interfaces fail over with it and their interfaces on the new node become active.
