We have a environment where we have one CAS and 2 Primary site (P01, P02), each Primary for 5 DP at different location, we have Direct access in place but no IBCM.

Just trying to understand when user's machine of PR1 site is over the internet which DP it would connect for downloading the content.

These clients would be treated the same way as any other clients. You need to create a boundary (IPv6 range) for the DA clients and add to a boundary group configured with the DP(s) you want t

Great.Thanks Gerry for your reply.

However have another doubt, do DA servers will have the option to specify what IPv6 range will be assigned to client machines. so that we could split the IP range to divide the load among all DPs.

That depends on how your Remote Access server and networking are configured. You'd have to check how it's been done but the role is geographically aware.

Thanks Gerry.

Or you could assign more than one DP to the boundary group to spread the load and create redundancy.
