Hi Praveen, if you take a look the the Integrated Domains document I shared you'll see several solution limitations listed. Those same limitations are not present in the Independent Domains model, and as such we find most customers ultimately arrive at Independent Domains as the right design pattern for their networks - you may not need multicast / IPv6 / L2HO / etc. initially but it's very likely one of those requirements will come up in your customer's network as time progresses. Please proceed with Independent Domains if possible, it's the same amount of hardware but a more flexible design pattern.
