Hi,
We have a WAN composed of 10+ VLANs and a configuration using a single central Microsoft DHCP service (10.0.0.10) broadcasting ip addresses to all network; directly in HQ and via Cisco Routers “ip helper” configuration on remote sites.
I ve installed a remote DHCP server (10.0.1.10) on one of those sites and i m willing to send the remote clients to that new DHCP server when theres a problem about central data center.
Also when central data center is down i want to update DNS server information on client side cuz i m planing to use alternate servers for each critic service. And i m keeping that alternate configuration on a DNS server thats normally unreachable.
To be able to do that i need to enter a secondary DHCP configuration on cisco devices and i m not able to figure out if its possible?
Also i need to tell disaster microsoft DHCP server to broadcast 10.0.x.20 as DNS information.
central dhcp 10.0.0.10
disaster dhcp 10.0.1.10
central dns 10.0.0.20
disaster dns 10.0.1.20
