A Cisco Nexus 7000 switch is used with the VRF feature to provide separation between the inside and outside interfaces of a transparent firewall.
The VRF RED is used for an untrusted network of the virtual data center, and it is connected to the outside interface of the firewall. The VRF GREEN is used as a trusted network of the virtual data center and is connected to the inside interface of the firewall. Subnet 10.10.10.0/20 is used to communicate between two VRFs across the transparent firewall.
The firewall is configured correctly. The network administrator configured the VRFs and IP addressing correctly, but you are still unable to communicate across the firewall.
What is a likely cause of the problem?
A. This topology is incorrect. A transparent firewall cannot be used with VRF.
B. On Cisco Nexus 7000, policy-based routing is required to communicate between two VRFs.
C. The issue is related to software licensing; an Enterprise Services license is required on Cisco Nexus 7000.
D. The issue is related to the MAC address of the SVI.
E. The issue is related to keepalive, which is not supported on the SVI.
