Asa transparent mode

The_guroo_2 — Tue, 12 Mar 2019 07:34:49 GMT

Guys few confusion regarding ass transparent mode . We have a networks which we need to segregate (2 vlans ) as they are on same subnet diner decided that add an asa between them and make it transparent mode I have few questions

1 BVi can only be created in multiple context ? Or it can be used in single context as well so if we make asa transparent do we have to confuse context or not ? Secondly I m confused abt BVi I know what it is but not sure it can be used in single context secondly how we can manage it way of managing in from inside network ?

Thanks

Hi there! My answers below:

1) Mulitiple Contexts are NOT required for BVIs. Virtual contexts simply allows you to take one physical device and "slice" it into multiple virtual devices. Here is more information about multiple-contexts:

2) To create BVIs and run the ASA in transparent mode you need to change the ASA mode from "routed" to "transparent" mode with the following command:

firewall transparent

3) BVIs are bridge virtual interfaces and they allow you bridge two more interfaces together. For more information about that and configuration of transparent firewalls please check the link below:
