At the moment I have a following setup: http://img69.imageshack.us/img69/4227/252530.png
The ISP-A connection is the primary link and the ISP-B connection(over WiMAX) is the backup one. In case the primary link fails, I physically plug out the fiber-optical converter cable from my Cisco router(Cisco 1841) and insert the one from WiMAX device. In addition, I reconfigure the IP parameters in the router. This is probably the most manual "multihoming" possible :) I'm ready to upgrade my router so it supports two Ethernet cables. a) Is it somehow possible to automatically switch over to another one connection in case the primary one fails. For example ping www.google.com over a period of time and in case it doesn't respond, automatically switch over to backup connection? b) Is it somehow possible to have one static IP address while using the services of two different IPSs? While I'm afraid the latter is impossible, the first automatic switchover should be somehow doable, shouldn't it? As I told, I'm ready to invest into new equipment if it's necessary. PS I'm aware, that probably the most elegant solution would be a BGP sessions with ISP routers over different last-mile technologies. This would provide fast failover and I could use one IP address. What are the best practices for multihome connection over two different ISP's? regards, martin _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
