Question
BOOTP Forwarding
I"m working with someone who is attempting to use a NetBoot server for imaging Macintosh workstations. NetBoot works off BootP which is a broadcast and is not automatically forwarded between subnets. Based on the research I've done, I need to utilize the ip helper-address command to pass BootP traffic to the NetBoot server. We're currently using the ip helper-address command to forward dhcp traffic to our dhcp server. My question is, can I have multiple ip helper-address commands on the same interface? If so, is it correct in that if a BootP broadcast is issued, it will first forward to the dhcp server because that is the first ip helper-address statement. It will then notice that the server is not responding to BootP and will then forward to the next ip address in the ip helper-address statement?

I believe you can have up to six ip-helper address per interface. what will happen is when the device that has ip-helper enabled receives the packet it will forward it on to both address as a unicast.
