Question 27: Refer to the exhibit. When running EIGRP, what is required for RouterA to exchange routing
updates with RouterC?
A. AS numbers must be changed to match on all the routers
B. Loopback interfaces must be configured so a DR is elected
C. The no auto-summary command is needed on Router A and Router C
D. Router B needs to have two network statements, one for each connected network
Correct Answer: A
Explanation:
Here we required same autonomous system between router A,B,C.Routing updated always exchange
between in same EIGRP EIGRP autonomous system.you can configure more than one EIGRP
autonomous system on the same router. This is typically done at a redistribution point where two
EIGRP autonomous systems are interconnected. Individual router interfaces should only be included
within a single EIGRP autonomous system. Cisco does not recommend running multiple EIGRP
autonomous systems on the same set of interfaces on the router. If multiple EIGRP autonomous
systems are used with multiple points of mutual redistribution, it can cause discrepancies in the
EIGRP topology table if correct filtering is not performed at the redistribution points. If possible, Cisco
recommends you configure only one EIGRP autonomous system in any single autonomous system.
