CSM redundant bridged mode - alias IP required?

[dknoezinger]

Hi! I am a little bit confused about the configuration guides concerning csm + fwsm

+ csm bridged mode. in my opinion when using bridged mode with the csm i do not really need any alias ip configuration - neither in the client vlan nor the server vlan. in bridged mode the csm does not route - thus i won't have any routes pointing to the csm. why are there always alias ip configurations in redundant bridged mode config guides? can somebody please clear that up for me? is there any other function of the alias IPs that I need them for?

Thanks,

Daniel

Daniel,

In general, if no router is present on a server-side VLAN, then each server's default route points to the aliased IP address. In the case of bridge mode, like you have, there is no need for the alias ip.
