The correct answer is B. Advertised changes.

EIGRP (Enhanced Interior Gateway Routing Protocol) is a routing protocol used in computer networks to help routers dynamically discover paths and efficiently route data between network nodes. EIGRP routers build and maintain a topology table that tracks the routes to all the destinations in the network.

EIGRP routers use hello messages to discover neighboring routers and establish a neighbor relationship. Once neighbors are established, they exchange routing information using update messages, which contain information about network topology changes.

Whenever there is a change in the network topology, such as a link failure or a new link being added, the router with the change advertises it to its neighbors in an update message. The neighbors then update their topology tables and routing tables accordingly.

The function that allows EIGRP peers to receive notice of implementing topology changes is the advertised changes function. This function ensures that all routers in the network are aware of topology changes and can update their routing tables accordingly.

The successors function in EIGRP refers to the routes with the best metric to a particular destination. Goodbye messages are used by EIGRP routers to inform their neighbors that they are no longer available. The expiration of the hold timer is used by EIGRP routers to detect when a neighbor is no longer available.
