Explain how the routes in the table are being affected by the status change on interface Ethernet0.

A.
The router is poisoning the routes and multicasting the new path costs via interface Ethernet1.

B.
The router is receiving updates about unreachable networks from router that are connected to interface Ethernet1.

C.
The router is poisoning the routes and broadcasting the new path costs via interface Ethernet1.

D.
The router is requesting updates for these networks from routers that are connected to interface Etherne1.

Explanation:

Poison reverse: When path information becomes invalid, routers will not immediately remove them from the routing table, but use 16, an inaccessible metric value, to broadcast it out. Although this increases the size of the routing table, but is helpful for the elimination of routing cycle, it can immediately remove any loop between adjacent routers.

The purpose of route poisoning is to avoid problems caused by inconsistent updates and to prevent network loops. According to exhibit, the interfaces went to the down state so the affected routes were poisoned and removed and an update to the multicast IP address of 224.0.0.9 was sent on interface Ethernetl.
