Explanation: Functions of OTV

Maintains a list of overlays

Maintains a list of configured overlay parameters such as name, multicast address, encapsulation type, authentication, and OTV feature sets

Maintains the state of the overlay interface

Maintains the status of OTV VLAN membership from Ethernet infrastructure and the state of the authoritative edge device (AED) from IS-IS

Maintains a database of overlay adjacencies as reported by IS-IS

Maintains IP tunnel information and manages the encapsulation for data sent on the overlay network

Manages delivery groups (DGs) for each overlay by snooping multicast traffic and monitoring traffic streams for active DGs

Configures, starts, and stops the OTV IS-IS instance

Interfaces with IP multicast to join provider multicast groups for each overlay
