IOS SLB inservice standby

Hi,

I would like to know what is the main purpose of use the "standby" at the "inservice standby <group>" defined under the virtual server?. It's just a information ("as description") to associate the HSRP standby into this virtual server or it's have another function?.

Thanks,

Marcelo

Marcelo,

IOS SLB "inservice standby" is used where you require stateless redundancy for vservers across 2 SLB routers or switches. Using this command makes the vserver state follow the HSRP state of the relevant interface, to prevent the situation where one router is processing routing traffic but the other router is active and listening for traffic directed to the vserver address. It is much more than a description for the HSRP group, it is the mechanism to allow redundancy to function.

Re: IOS SLB inservice standby

In a topology where you just have 2 servers and you wish to slb them, how can you provide redundancy of the slb itself ?.

As I understood you cant have 2 slbs (stand and act) for just 2 servers.

Maybe I missed someting here,

Giovanni
