ASA active standby IP addressing

[west33637]

when configuring high availability does the active/standby IP on the interface have to be contiguous?

example:

int gi0/0

ip address 10.10.5.36 255.255.255.0 standby 10.10.5.40 ---- can I do that?

or does it have to be

ip address 10.10.5.36 255.255.255.0 standby 10.10.5.37

thx

The active/standby IP addresses does not need to be contiguous. As long as they are in the same subnet, it is OK.

In your example, you can use either of the ip addresses for the standby ip address.

Hope that answers your question.
