Q

A customer is working with a service provider when planning to deploy OTV between two data centers. The customer does not know how the service providers network is configured. What should the customer do to optimize the new OTV solution?

A. The customer doesn’t need to do anything, OTV works transparently over service provider networks.
B. Reduce the MTU on the OTV VLANs to 1,458 to accommodate for the additional 42 bytes of overhead.
C. Increase the MTU on the Join interface(s) to enable jumbo frames.
D. Reduce the MTU on the OTV VLANs to 1,436 to accommodate for the additional 64 bytes of overhead.

A

A customer is working with a service provider when planning to deploy OTV between two data centers. The customer does not know how the service providers network is configured. What should the customer do to optimize the new OTV solution?

B. Reduce the MTU on the OTV VLANs to 1,458 to accommodate for the additional 42 bytes of overhead. > 14-byte Ethernet header, 20-byte IP header, and 8-byte OTV shim.

OTV verification - show Mac-address-table should show remote endpoints.
The OTV uplink physical interface just has IP address, routing protocol enabled, and IGMP configured. The overlay interface has the config, plus extended VLANs may require MTU lowered 42 bytes for OTV overhead.
Site VLAN is for local communication between OTV edge devices.
Need PIM enabled on interface? No, only IGMP.
