we have someone looking at doing GLBP on a router with connections to a Cable ISP and a DSL ISP. They want a seamless failover for outbound traffic whenever one link goes down.
Is there any advantage to running BGP and having a public AS number if neither ISP will advertise the others IPs?
The ultimate goal is to have the failover traffic on teh inbound side still be able to reach internal web servers that have teh public IP address of teh Cable provider if the cable link is down. I think a solution may be to use the router as the authoratative DNS server for the network and use a very short TTL so that if the Cable provider goes down the router sends out the DNS update to start using the DSL providers static IP to reach the web server. The problem is even using this method there could be a significant delay in the updates and the web server would be unreachable for severla minutes to several hours.
Any ideas on how to best accomplish this? All replsies rated! Thanks in advance!
