How to change LAN defautl gateway (ISP) automatically to another gateway when goes down?
I was just wondering, if its possible this scenario. I got a client that has two buldings; each of this buildings are going to have one blades systems for virtualization of the servers, synchronizing constantly using a software that makes this. Each bulding has the same ISP provider but diferrent lines and different public ip addresses. The two buildings are gonna go to one of this line to the internet and the other is for backup only, in case the default one goes down. This can be done manually by changing in the DHCP the default gateway, but the client is asking if this can be done automatically, because down time for them cost thousand of dollars. The scenario in infraestructure is = two buildings having domain controller on each one, one DHCP server, they are going to be talking via a T1 line Point-to-Point. One of the buildings has a T1 line to the internet with a public address and a ISA Server for routing and firewall and the other building the same thing. Any help will be appreciated.

This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
