remote address space migration for several wan sites without connectivity loss
Posted on 2004-04-08
I'm looking at a customer who needs to migrate from their existing 172.x.x.x space to a 10.x.x.x space. They have several remote locations connected via frame relay. They have admins at the remote sites who can re-ip their servers and desktops but thay want the routers changed over all from the central site. I'm looking for advice on how someone at the central site could reconfig all the remote routers to the new ip space without loosing connectivity back ot the central site in the process. I'm thinking I could use secondary iP addresses on all the wan interfaces to bring up the new ip space then delete the primary ip addresses after all the secondary ip addresses are up and configured. Would appreciate any comments, suggestions, or solutions...
