Could anyone advice me:
I have two contents and they both use interface G0/1 as outside interface; can I configure it on same subnet?
for example:
on contents admin:
interface g 0/1
nameif outside
security-level 0
ip address 10.1.1.10 255.255.255.0 standby 10.1.1.2
on contents admin2
interface g 0/1
nameif outside
security-level 0
ip address 10.1.1.100 255.255.255.0 standby 10.1.1.102
Any comments will be appreciated
Thanks in advance

Hi
I dont think you will be able to configure the same ip address on both the interfaces..

not same ip address, different ip address, but same subnet.
I am trying to configure virtual firewall (with load balancing) using two css11506s.
so, I would like to know if the outside interface for both contents (with active/active) can be same subnet.
I have got impress that they have to be diferent subnet. But, when I do configuration, I can put them on two different ip addresses but same subnet.
Could I get confirm:
if I can using same subnet on outside interface for two contents?
Any Regards

HI .. from teh CCSP book it reads ..
The Security Appliance allows interfaces to be shared between contexts. This is allowed only
with adherence to the following guidelines:
■ The Security Appliance must be in routed mode.
■ The shared interface must have either a unique IP address for each context or a unique
VLAN for each context that will be using it.
So in your situation is it OK however you need to carefully planing NAT as this will tell the ASA which context to send the incoming packets.
I hope it helps .. please rate it if it does !!!
