Refer to the exhibit. You have a suboptimal outbound routing issue in the datacenter. Which two options you can use to resolve the issue? (Choose two)
A. On the OTV VDC, configure an OTV MAC route filter that prevent the virtual FHRP MAC address forwarded on the overlay
B. On the OTV edge devices, configure a VACL that prevents FHRP hellos from being forwarded
C. Configure the same FHRP priority on all the OTV edge devices in both sites
D. Remove the VLAN from which FHRP hellos are sent from the extended VLAN range
E. On the OTV edge devices, configure an IP ACL that prevents hosts from reaching the FHRP master router on the other site
Correct Answer: AB

To prevent the virtual MAC addresses from causing MAC moves and allow for a cleaner design, an OTV route-map must be configured. This route-map must match the virtual MAC of the FHRP protocol used. You will need to make MAC ACL and IP ACL extended. In case of Nexus switches you can use VACLs for this.
