I'm getting ready to roll out a second dhcpd server with failover operational:

It's simple enough to set up but since I'm currently supporting multiple subnets from the one server I am not clear about the ip helper-address in IOS. Currently of course it's just the one line ip helper-address 1.2.3.4Should I add a second helper-address line to the config, or is it better to change the existing line to a broadcast address (1.2.3.255, assuming a /24)? Has anyone used this in production?
