Transparent user context in an ASA with routed user contexts

[SabeelShakeel00430]

Hi,

I'd like to know if its possible to create a transparent context on an ASA that has routed contexts. I've not seen anything that suggests the two context types can be mixed.

If its possible to do so, then I will need to trunk two vlans - in this example i'll use vlan 1 and vlan 2. i understand in a transparent set-up a BVI will need to be created per vlan and would like to know if its possible to have the same inbound and outbound vlan in a BVI eg:

BVI1:

inside interface - Vlan 1 

Outside interface - Vlan 1

BVI ip address - 1.1.1.1

BVI2:

inside interface - Vlan 2 

Outside interface - Vlan 2

BVI ip address - 2.2.2.2

Best Regards,

Sabeel

To answer the first part of your question, its supported from 9.0 and above to have mixed modes of firewall in multiple context

Also tested this in lab:

ASA5585-X-1# sh firewall
    Context                 Mode
admin                       Router
test                        Transparent
ASA5585-X-1#

Hi,

Thank you so much for this. Would this mean i can also create bridge groups with the same vlans as mentioned previously or would I still need a different external vlan ?
