Just wondering what does OTV run on? Directly over IP, of UDP or TCP. When I did google search, I see that OTV uses TCP/UDP ports 8472. But the OTV documents say it only adds 42 byte overhead. With 42 bytes, I could not account for TCP or UDP headers in the encapsulation.
Has anyone have full capture of OTV encapsulated packet in Wireshark or something. I wanted to know how OTV is transported over IP network.
