We have a project to migrate services from one Data Centre to another within the UK for a large organisation.
We currently have a large corporate Verizon MPLS WAN with 622mb links into both Data Centres (old and new).
Due to the large number of servers our customer would like to keep the same IP addresses in use on all servers - and due to the large number of servers we won't be able to move them all in one go. This means we will need to have servers on the same IP subnet in different locations at the same time - i.e. some in the old Data Centre and some in the new Data Centre.
Due to the physical distances involved (approx 200 miles) a traditional LAN extension is not available. We've also asked our WAN provider (Verizon) about a L2 Tunnelling service to effectively span the Vlan/subnet across both sites but this service is only available in the US/Canada and not the UK.
So my question isâ¦ â¦
Does anyone know any way of tunnelling the same Vlan or subnet between the two sites using our current WAN and any Cisco routing/tunnelling methods.?
Or, has anyone used any other WAN provider in the UK or Europe who can deliver this kind of service.?
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
