A. The VRRP needs to be implemented on the MDS switches
B. The VRRP protocol will represent the inbound link as a VIP
C. The HSRP and VRRP protocols make no difference with the MDS FCIP link
D. The VRRP protocol is encrypting all of the FCIP traffic and striping the FCIP headers as part of the encryption process
