I have searched all over Cisco & Google and havent found anything that tells me straightforward what features are included with the ASA5540-BUN-K9 as opposed to just the ASA5540-K8. The only difference I can tell is 3DES/AES.
I am concerned with being able to run the firewalls in an A/A configuration and possibly doing VPN clustering. In addition, what upgrade licenses would I need to be able to run more than 2 security contexts?
Any help or links would be greatly appreciated.
