Using the Local Director "alias ip address" command

[a.proctor]

I believe it is possible to have real servers in a different subnet to the local director virtual address by using the "alias ip address" command. This eliminates the need to use a router between the Local Director and the real servers. Does this mean that the Local Director is routing between subnets? Do the real servers use the Local Director alias address as their default gateway? Can someone provide an example config using the "alias ip address" command?

no, the local director will not route. there are two ways to make this work.

1

the router on the front side of the local director must be configured with a secondary ip address from the real server subnet plus add the alias command

or

2

use the alias command, plus each real server must be configured with a static ARP entry. the ARP entry is for the ip address of the servers configured default gateway and the MAC address of the router interface.
