What are two reasons to select OTV as the DCI solution to connect multisite topologies? (Choose two.)

The correct answer is A. It propagates hosts reachability without support of traffic flooding. E. It constrains HSRP hello messages to each data center.. OTV introduces the concept of “MAC routing,” […] it is justified by the need to limit flooding of Layer 2 traffic across the transport infrastructure. The last capability introduced by OTV is to filter First Hop Redundancy Protocol (FHRP-HSRP, VRRP, and so on) messages across the

Explanation

OTV introduces the concept of “MAC routing,” […] it is justified by the need to limit flooding of Layer 2 traffic across the transport infrastructure. The last capability introduced by OTV is to filter First Hop Redundancy Protocol (FHRP-HSRP, VRRP, and so on) messages across the logical overlay. TV_Intro/DCI_1.html
