Hi,

we have 3 internet Leased Line connectivity. each link is connected  with cisco internet router & below ASA as per below.

Internet link (ISP 1)--->Cisco Internet Router--->Cisco ASA 5525X----->Core switch--web server1, Mail server, site to site VPN,MX primary server etc.

Internet link (ISP 2)--->Cisco Internet Router--->Cisco ASA 5520----->Core switch--proxy server, secondary sell server, MX backup server   etc.

Internet link (ISP 3)--->Cisco Internet Router--->Cisco ASA 5510----->Core switch--LABMATE Server, SAP Server, Lync 2010, Remote client VPN etc.

Problem: if any ISP link get down, respected server connectivity are down from internet world & business affect.

Hi,

I see that the ASA devices are different. Is there a single router in the network connecting to all the ASA devices ?

In that case , IP SLA on the router would be the most efficient solution.

Thanks and Regards,
