Not sure what you are asking, but let me explain

In Windows 2003:
- The IP resource is moving with the Group to the other node, comes online,
after that it is the (R)ARP mechanism which will ensure the traffic is
received by the cluster node... standard IP networking (no "redirection")

In Windows 2008, and nodes on different subnets:
- There are two IP resources in the group, with an OR logical to the Network
Name, both IP resources will move to the node, but only one (for the correct
subnet) will come online, then the network name will come online. As now the
IP address has changed the "re-direct" (not really redirecting) is done by
DNS registration, so it relies on DNS to function properly. Same name in
DNS, IP address changed in DNS -> Clients can connect to the same name, new
IP address. Note: this might take some time to replicate the registration
around all DNS servers, as well as you might experience delay because of
local DNS caching.


Does that answer your question ?

PS, none of the two methods above are actually using "redirecting", it is
using standard IP networking technologies such as (R)ARP and DNS
registrations. Windows Failover Clustering is not really using any
"redirecting" technologies.
