Hello @Ibrahim Jamil 

VxLAN and OTV are both supported by Cisco platforms like Nexus 9k, 7k and CSR1000v.

Also, Cisco Nexus7K series supports VXLAN with BGP EVPN for Data Center Interconnect purposes.

Friends , a Couple of inquiries 

1. though I noted OTV is much easier than VxLAN BGP EVPN from the configuration stand of points as a DCI Solution ,Freinds  Do u agree?

2. Any specific Use Case to go VxLAN BGP EVPN over OTV as a DCI Solution

[balaji.bandi]

Depends on use case - before there is no VXLAN until rencent decade of invention - that time cisco propriery OTV only available - other than VPLS  / dar fibre DC to DC connecvity which is expensive

as technology evolve - VXLAN in picture and its open standard

more informaiton can be find here :

VxLAN BGP EVPN over OTV 

Not that i have deployed this and work i guess here (may be never heard or tested)

Either you use OTV or VXLAN BGP EVPN (not missing both)

Note :  as i mentioned one of the  post you need here in the forum for Long, google is always help information what you looking ? until you stuck any configuration issue you can post here ask for help, Cisco has huge documentation and deployment guides posted.

This help you and community if you like to contribute to cisco community.

I have also BLOG down below my name , how to post question to community.

Hello @Ibrahim Jamil,

High level:

-- Configure OTV on the edge devices that connect the two data centers. This includes defining the overlay interface, configuring the OTV control plane, and setting up the extend VLANs.

-- Establish BGP peering between the data center switches across the OTV network. Ensure that the BGP peering is established over the OTV interfaces.

-- Configure the BGP EVPN instances to advertise MAC and IP information over the OTV network. This enables the exchange of endpoint information between the data centers.
