config active/active statefull failover on ASA5520 v7.2

[julxu]

I have two asa5520 and two contexts. I am going to configure as.

- multiple mode

- trunk on int G0/1 for two internal

g0/1.1 context1

g0/1.2 context2

- I should trunk on int g 0/0 for two external.

g0/0.1 for context1

g0/0.2 for context2

Can I use same subnet for external interface? That means:

- external: no trunk

interface g 0/0

nameif outside

ip address 10.1.1.1 255.255.255.0 standby 10.1.1.2

If so, how to configure, Please advice.

Any comments will be appreciated

Thanks in advance

Hi .. I believe you can, but you need to be aware that packets passed by the physical interface are not tagged and so you need to make sure the switch port is configured with a native VLAN ID which will correspond to whichever VLAN you are using as your external range.

I hope it helps .. please rate it if it does !!!
