global load balancing/active active vip and virtual interface redundancy

Is there a way to configure both of these technologies without exposing the external addressing to the internal network? I have active active within the data center and would like to have active/active across two data centers but I don't see any way to use internal addressing for my content rules and still use them for dns unless I can specify records without using content rules. Thanks.

Re: global load balancing/active active vip and virtual interfac

Hi Victor,

In response to your questions regarding doing Active/Active GSLB using VIP and interface redundancy.

Rule Based GSLB will not work with VIP/Interface

redundancy.

The reason is because the CSS can not set up an app session to a redundant

interface, it needs to set the app session up to a real interface. Thus, a

full mess topology must be used for GSLB and vip/interface redudancy.

Bug ID CSddw27861 reported this problem and engineering added the command

"ap-kal-vip" to support a full mess topology. This command can only be used

under zone based GSLB and not rule based.

The syntax for the command would be:

dns-record a www.work.com 5.5.5.5 0 single kal-ap-vip 1.1.1.1

rule/ACL based GSLB with vip/int redundancy will not work.

Regards,

Mark
