We currently have 4 physical sites within our organisation. These sites are Heathrow, Norwich, Wales and Ipswitch. At the moment the site links which are configured are in a mess. There are five site links. One is a duplication, this is Heathrow - Ipswitch seems to be listed twice with a cost of 100 and interval of 15min (with only these two sites in it) Site link is just called a different name. Third site link link which contains Heathrow, Norwich and Wales. Fourth with just Wales by itself. Fifth with Heathrow and Norwich.
Sites Norwich, Wales and Heathrow are all on MPLS, Ipswitch is connected via VPN tunnel to Heathrow.
I want to simplify the site links. Would a good design be to have Norwich, Wales and Heathrow all in one Site Link and then a separate site link for Ipswitch and Heathrow, or could someone advise best practice on this? Bridge all site links is ticked and site links are all currently IP site links.
