Two different subnets assigned to single Bridge Group

Hi ,

We are deploying two Cisco 5585 in transparent mode and multiple contexts. they are runnign Active-Active failover.

There are a lot of VLANs need to be added in the contexts, we are trying to use least contexts to fulfill.

ASA supports 8 bridge groups for each contexts, and maximum 4 interfaces for each bridge group.

We have assigned four interfaces in different VLANs , set two of them as a pair with one IP subnet and the other two interfaces are in another IP subnet.

For example :

Bridge group 1:

inside1  and  outside1    ------->   192.168.1.0/24

inside2  and  outside2    ------->   192.168.2.0/24

However, we can only make one subnet(VLAN pairs ) work when the BVI is set to that IP subnet.

If the BVI set to  192.168.1.0/24, the inside1 and outside1, the other pair not work. If the BVI set 192.168.2.0/24, then only inside2 and outside2 work. 

Since the BVI can only be assigned to either of the subnet, Is it possible to make both vlan pairs work ?

Or we only can have one subnet in one bridge group ?

Thanks

Veon
