OTV using Unicast adjacency does it still need pim and msdp


We have a working OTV enviroment.  I have been asked to created a second overlay interface for a DMZ enviroment

Where currently using

otv adjacency-server unicast-only. 

but i still see a number PIM interfaces and we also use the MSDP conficugration which i presumed to be only for the Multicast mode

Can some one please clarify if using unicast mode do i still provision all PIm and msdp confguration  to get unicast configuration working

documentation is unclear


PIm information is on physical interface between both DC  and interconnect between both 7k Switches

I am not very sure on how Nexus works related to OTV unicast, but in case of ASR1K you definitely do not need any multicast configuration when bringing up OTV using "adjacency server unicast-only" option.

If you need configuration details related to ASR1K, I have a small blog wherein I have configured the same [both for unicast / multicast OTV cores].

Do have a look if needed:
