Challenges with LAN ExtensionsReal Problems Solved by OTV

• Extensions over any transport (IP, MPLS)

• Failure boundary preservation

• Site independence / isolation

• Optimal BW utilization (no head-end replication)

• Resiliency/multihoming

• Built-in end-to-end loop prevention

• Multisite connectivity (inter and intra DC)

• Scalability VLANs, sites, MACs

ARP, broadcasts/floods

• Operations simplicity South Data
