CSM issue when using bridge mode

[yueric]

I have 2 CSM installed on 2 6509 each,and configured as bridge mode.One is acting active,another is standby.I know that client and server vlan have to use same IP,but I'm confused that the IP on standby CSM,does it need to differ from active CSM vlan IP or not?

Hello,

yes the ip adresses of the vlans on both CSM have to be different as you would have dupplicate IP-Adresses in any other case (not talking of the same IP-Adress in vlan1 and vlan2 configured in bridged mode). You should use the alias command to make the gateway redundant (only if this is needed in your scenario). In regards of the VIP-Adresses they have to be the same for failover purpose. I guess you know that you need the failover vlan too.

Kind Regards,
