You are attempting to connect a NetApp ONTAP cluster to a very complex network that requires LIFs to fail over across subnets. How would you accomplish this task?
A.
Configure an equal number of UFs on each subnet.
B.
Configure VIP LIFs using OSPF.
C.
Configure VIP LIFs using BGP.
D.
Configure a I IF failover policy for each subnet inside a single broadcast domain.
To accomplish the task of enabling LIFs to fail over across subnets in a complex network, you should:
C. Configure VIP LIFs using BGP.
Virtual IP (VIP) LIFs, combined with the Border Gateway Protocol (BGP), allow LIFs to fail over across different subnets by announcing the current location of each VIP LIF to routers through BGP. This setup is designed to meet the failover requirements of complex, next-generation data center networks.
