OTV mroute queries

Hi Firends,

 

I ahve configured OTV in our rental rack (DCRACK5). I have succesfully configured the OTV and it is working properly and able to communicate DC2 server. But when I check the OTV mroute, I am always nothing getting result. Kindly let me know, what is my mistakes in OTV mroute configuration.

DC1-N7K1:

==========

feature otv

otv site-vlan 60

  otv join-interface port-channel1

  otv control-group 224.1.1.1

  otv data-group 232.1.1.0/24

  otv extend-vlan 10, 20

otv-isis default

otv site-identifier 0x101

interface port-channel1

  ip address 10.71.72.71/24

  ip router eigrp 71

  ip igmp version 3

  ip igmp join-group 232.1.1.1

    the multicast you testing is native multicast because you used the join interface for testing. it's not the OTV encapsulated multicast, you can test with the mcast behind the OTV internal interface and check the command again.
