Usage Guidelines This command allows you to place the CSM on a different IP network than real servers without using a router.
If the ICMP protocol does not terminate, you may need to set the idle timeout of these connections. The alias IP address in the CSM serves three purposes:
•It is a shared next hop (gateway) for two CSMs in the redundant configuration. The servers should point to the alias as the default gateway. The Route Health Injection (RHI) service would be using the alias IP address as the next hop when inserting a route.
•If ping is destined to the alias IP address, the CSM sends the reply back to the source MAC. This reply is useful when performing an ICMP probe from one CSM, across a firewall farm, to the other CSM alias address.
•In the Global Server Load Balancing (GSLB) configuration, the alias IP address is the destination VIP for the DNS request.
