Using hte same IP Adresses at multiple sites during move / "Extended LAN"
A customer has two datacenter sites A and B connected over a corporate WAN.
Site A is using IP-range IPA, B is using range IPB.
Both sites will be moved to a new site C, the IP-range is not yet decided.
Is it possible to make the move activities more flexible, to extend the LAN of site A and site B to site C during the move (site C will be connected to A and B, either via the corporate WAN or a separate leased line)? The idea is to use the ranges IPA and IPB in site C and to avoid changing all IP-adresses. At the same time the ranges will still be in use at sites A and B, but individual IP-addresses will NOT overlap!!! The move will not be done in one day or weekend, but some months.
After the move, sites A and B will disappear.
I heard of a technology called "LAN extension", but could not find something on the Cisco Web.
Re: Using hte same IP Adresses at multiple sites during move / "
I suggest you use VLan to configure new site C. You will have 3 VLan that routing traffic. Don't forget to configure default gateways for each VLan in your switch router. You may reconfigure machines in each VLan after moved.
