I have two T1 lines from different providers and the requirement is to\nhave the end-users default route be the one ISP and the servers\ndefault route the other ISP. Additionally, there needs to be a way\nfor automatic failover should one of the lines fail. The final\nchallenge is that all the traffic is coming from a 5510 ASA. The\nswitches on the inside of the ASA are unmanaged but the servers\nconnect to one switch and the workstations another so I can physically\nseparate them and configure an interface on the ASA for each group.\n\nI know it is a relatively simple task if all traffic goes out one line\nand the other is strictly failover. The crux of a solution like this\nwould be a tracked default route, multiple route-maps, and multiple\nNAT statements. However, for the requirements mentioned above I am\nthinking of using route-maps setting the next hop of the preferred\npath and then the secondary path. The servers with static mappings\nare just hosed unless someone manually configures them with the\nsecondary ISPs IP addresses or have an alternate config ready. I am\nnever thrilled with a solution that requires manual input but it may\nbe the chosen path. I would set IP precendence (or some other QoS\nmarking scheme) for the workstation traffic to be able to distinguish\nit from server traffic and thus determine what route it takes.\n\nI think all in all BGP would be the best bet provided I can get a /24\nfrom one of the providers and both support BGP. However, just in case\nI am lining up other non-BGP alternatives.\n\nOpen to all thoughts and ideas. Thank you.
