So for whatever interface they use for communicating on the Internet,
they use that same interface to talk with the director? If the
realservers need to communicate over the Internet, they need some more
information than a single IP address that will never marry a MAC
address. For LVS-DR, it is necessary to have 2+ physical interfaces?
For LVS-DR you need only one physical interface on the director and each
real server.
Consider the following example:
End client
|
Internet
|
|
---- 216.74.150.10 (director)
|
---- 216.74.150.11 (real server 1)
|
---- 216.74.150.12 (real server 2)
|
---- 216.74.150.13 (real server 3)
The end client sends a packet to the virtual service. Then the director
selects the real server and forwards the packet. The real server
directly replies to the end client.
In this example the director and the real servers use public IP addresses.
