I have the following commands configured on my cisco2821 G0/0 interface:
ip adddress x.x.x.x x.x.x.x
ip helper-address 172.24.1.1
ip helper-address 172.24.1.2
Can I know how will this ip helper work? Will it always use the first dhcp server (172.24.1.1) to request for IP address? Then, the second one will only be used when the first one failed? Or, just round robin?
