ASA Dual ISP - VPN L2L?

[BERNHARD FIEGLMUELLER]

Hi

I have an asa cluster where L2L Tunnels are configured.

Now i want to have an Backup ISP at the ASA side.

What i have done is SLA Monitoring for the ISP backup if the primary ISP fails.

But how can i cant the crypto map to the "backup interface" i think that it is not possible to have the same crypto map on 2 interfaces.

I found much about this question in netpro, but not really a solution.

regards

Bernhard

Hello!

I have the same issue but the swap from the primary to the backup works well, but the swap form the backup to the primary is a problem because I have to active SAs with the same cryptodomain and that's why the the asa don't know which SAs should take it.

Here a configuration output:
