ASA 5520 backup ISP connection

I have 2 ASA 5520's and I have 2 ISP connections. 1 ISP is the primary and the 2nd will be uised as a backup. I know that with the 5505 security plus you can do ISP backup. IS this possible with the 5520 and is this the best way to configure the backup ISP link? Is there another way of doing this eg if I don't have a switch to create a seperate vlan between the firewalls and the ISP routers?

Thanks in advance

Dual ISP links are supported starting in ASA software version 7.2. You can find the details here:

I have seen that document, but can this be done using two ISP's and a failover pair of ASA5520's?

7.2 PIX software supports Standby ISP Support which is standard software build on the 5505 and if you've got 7.2 on the 5520 you're in luck with that also.

Re: ASA 5520 backup ISP connection

Is it possible to implement Failover and Dual-ISP Backup without connecting the vlan 2 and vlan 4 interfaces to a switch? Can you connet these directly to the ISP's router interfaces?
