Refer to the exhibit. An architect must design a solution to connect the network behind R3 with the EIGRP network. Which mechanism should be included to avoid routing loops?
Outbound route tags can be used to filter redistribution and support EIGRP scaling with multiple EIGRP autonomous systems, as shown in Figure 3-10.
Figure 3-10
Figure 3-10 Filtering EIGRP Redistribution with Route Tags
External routes can be configured to carry administrative tags. When the external route is redistributed into autonomous system 100 at router A or B, it can be tagged. This tag can then be used to filter the redistribution of the route back into autonomous system 200. This filtering blocks the formation of the loop, because router A will no longer receive the redistributed routes from router B through autonomous system 200.
In the configuration snippets, when routers A and B redistribute autonomous system 200 routes into autonomous system 100, they tag the routes with tag 100. Any routes tagged with tag 100 can then be prevented from being redistributed back into autonomous system 200. This successfully prevents a routing loop from forming.
Within a routing protocol, your statement is correct. However, redistribution is in play here, the given answer is correct.
