A. B. C. D.D
The MC-LAG devices use Inter-Chassis Control Protocol (ICCP) to exchange the control information between two MC-LAG network devices.
https://www.juniper.net/documentation/en_US/junos14.2/topics/usage-guidelines/interfaces-configuring-multi-chassis-link-aggregation.htmlThe protocol used by two MC-LAG (Multi-Chassis Link Aggregation Group) devices to exchange control information is ICCP (Inter-Chassis Communication Protocol).
ICCP is a protocol used for communication between two devices in a redundant network topology. In the context of MC-LAG, ICCP enables communication between the two chassis in a multi-chassis LAG bundle.
MC-LAG is a technology used to provide redundancy and increase availability in network environments. In this technology, two or more network switches are connected in parallel to a single device, such as a server, using link aggregation. The device sees the two switches as a single logical switch, which provides redundancy in case of a switch failure.
In an MC-LAG deployment, the two switches need to communicate with each other to ensure proper load balancing and failover. This is where ICCP comes into play. ICCP allows the two switches to exchange control information, such as the status of LAG links and the status of the remote switch.
VRRP (Virtual Router Redundancy Protocol) is a protocol used for providing redundancy in the IP layer of a network. It is used to create a virtual IP address that can be shared between multiple routers. BFD (Bidirectional Forwarding Detection) is a protocol used to detect failures in the forwarding path between two routers. VCCP (Virtual Chassis Control Protocol) is a protocol used in Juniper Networks to connect multiple physical switches into a single logical switch.
In summary, the correct answer to the question is D. ICCP.
