You can, but you must go to the physical interface IP and not the virtual.


Hope that helps.

Nope, when running in multiple context mode VPN is not supported.

There is no mention of multiple contexts.

"Active active" implies multi-context.

Yes jilahbg

is right you cannot have VPN or Dynamic routing in an enviroment with multiple context. Failover A/A requires Multiple context

No it doesn't. I'm running an active/active pair w/o contexts.

Do you have one or 2 physical units? How does the output of "show failover" (or is it "show standby") look like?

I have configured 2 Cisco 5520 ASA's with active active and the main device

is up and the backup

is just in standby.

Ok. What you have is an active/passive-configuration. Since the second unit is "just in standby" its not really active.


Since one context can never be active in two units simultanously there is no way to "load-share" in that setup. The only way to balance the load between multiple hardwares is to have multiple context and spread the active-unit for each context over the hardwares.


I personally dont like Cisco calling it "active/active". It is what I define as sales b*llsh*t. :-)

Yes this is not being built as a load share but hot spare.

Well guys.


If you have 2 multiple context you can have 1 contect  active in an ASA and the another one active in the another ASA. So you will have them both active.!!!!!

Well, I'm not taking about VPN I.m taking about having 1 context active in an ASA and the another one in the another ASA.

You said that this method is not really active/active. But if we can have a context active in each ASA what would that be?

  • Cisco Employee,

1. VPN is not supported in multiple context. http://www.cisco.com/en/US/docs/security/asa/asa82/configuration/guide/contexts.html#wp1146747


2. For active/active configuration, multiple context is minimum requirement. You can have a few contexts active in the primary firewall and a few other contexts active on the secondary firewall.  This way you can use both the pieces of hardware at the same time and one doesn't have to be sitting there idle waiting for the other one to fail.

The scope of this thread is VPN-functionality in active/active. That is not possible.


Your scenario with multiple contexts balanced over dual hardware is what Cisco calls active/active. I´ve never said the opposite.


Whatever, I think we all agree now on what is possible and not. Otherwise, please have a look at my blog post: http://blogg.kvistofta.nu/cisco-asa-activeactive-failover/
