Hello, setting up a new vlan and in adding the IP helper found out that we now have 2 PXE servers(Altiris) on another VLAN and need to account for both. Can there be 3 IP helpers with 2 of them being PXE servers? will that even work?
int vlan x
ip address <>
ip helper-address <DHCP server>
ip helper-address <PXE server 1>
ip helper-address <PXE server 2> ????
ip directed-broadcast 101
access-list 101 permit udp host <PXE server 1> any
access-list 101 permit udp host <PXE server 2> any
The Cisco IOS can have multiple addresses listed with ip helper address pointing to each of the dhcp servers. With multiple helper-addresses configured, both servers would see the packets, but only the primary server for the scope would normally respond. This would depend on the servers end to distinguish which server would be the primary, there is not anything on the router or Cisco IOS that you can actually do to specify the primary or failover dhcp server.
