you mean both transparent and route in context mode :

look below guide lines :

Hello @sir_yrwins ,

you need a specific license if you want to run more then 4-5 contexts . You can have some contexts in routed mode and a few in transparent mode with specific limitations.

Hope to help

Hello
FYI-
ASA supports Single or Multiple mode as you are aware

• In single mode you cannot create virtual firewalls.
• In multiple mode you can create virtual firewalls.
• Each virtual firewall is called a context.
• Number of context that you can create depends on the license ( as stated by @Giuseppe Larosa )
• By default there are two built

Let's say that you have 2 Firewall contexts (CTX1 and CTX2), and you must have 2 contexts by default as parf of the base license.

CTX1 - Transparent Mode
CTX2 - Routed Mode

ASA1 to be active for CTX1 and standby for CTX2

ASA2 to be Standby for CTX1 and active for CTX2

OR

ASA1 to be active for CTX1 and standby for CTX2

ASA2 to be Standby for CTX1 and Active for CTX2

Convert ASA to multicontext

CiscoASA(config)# mode multiple

hi,

yes, the ASA can operate in multiple mode. issue a 'show mode' to confirm.

ASA comes with 2 security context by default and you'll need to buy a license if you'll need more.

issue a 'show version' to check the available context count.

use the 'mode multiple' in global config mode and it will ask to reboot to take effect.

all existing config will go to the 'admin' context.
