Secure Multimedia Controller Implementation Guide
The host IP address and the cluster MIP address must reside in the same
subnet.
High Availability (HA) configuration
In the HA configuration, each security zone requires three IP addresses: one
IP address for each physical SMC interface and a Virtual Router Redundancy
Protocol (VRRP) address. The VRRP address is hosted by the VRRP master
and floats to the backup if the master fails. Figure 4 on
page 36 illustrates a
typical SMC HA configuration.
IMPORTANT!
In a stand-alone configuration, the equipment residing on the Secure
Multimedia Zones uses the SMC Interface IP addresses as their
gateway address. For example, a CSE-1000 Signaling Server TLAN
Gateway address is the SMC TLAN IP address
IMPORTANT!
In a High Availability configuration, the equipment residing on the
Secure Multimedia Zones uses the SMC Virtual IP addresses as their
gateway address. For example, a CSE-1000 Signaling Server TLAN
Gateway.
When upgrading from a stand-along SMC to a High Availability SMC
installation, review carefully the IP addressing scheme so that the
equipment in the Secure Multimedia Zones do not need the gateway
addresses changed.
For example, when upgrading from stand-alone to High Availability
configuration, change the IP addressing so the existing SMC interface IP
addresses are used as the Virtual IP addresses when the HA config is
implemented."
