Tom is a network administrator for the P4S Ltd. He is having problems with redistribution routing loops between two EIGRP processes. After studying the configurations, he determined there is no filtering configured on the routes being redistributed. In order to avoid having a single point of failure, there are three routers configured to redistribute between the two routing protocols. Which one of the following items is a solution to minimize management complexity?
A) replace one of the EIGRP processes with an alternate IGP
B) reduce the number of routers redistributing between the two routing processes
C) build and apply a route filter based on the networks being redistributed between the two processes
D) use tags to control redistribution between the two processes

Using tags to control redistribution between the two processes helps to prevent routing loops by marking routes as they are redistributed, allowing routers to recognize and avoid re-advertising them back into the original routing domain.
