Re: Configuring HSRP w/secondary ip

Hi Friend,

Is there any specific reason you have configured same subnet ip address as primary and secondary and then you want HSRP to run for both the ip address?

You can configure hsrp for primary as well as secondary ip address using command

standby ip

standby ip secondary



*Pls rate all helpfull post
