Hi all,
I'm confused when deploying with multi DHCP relay having the same DHCP pool
.......................... ___________..................................
Client 1 ====== |SRX/MX/EX |====== DHCP server 1
Client 2 ====== |__________ | ====== DHCP server 2
For example, I have 2 DHCP client are client 1 and client 2 connect to Junos device (SRX/MX/EX) and the Junos device connect to two DHCP server 1 and DHCP server 2 have same DHCP pool such as range: 192.168.1.10 to 192.168.1.100.
When Client 1 request DHCP supply IP, the client 1 send DHCP Discover packet, after that Juno's device relay to two DHCP server. Two DHCP server also send back DHCP information for client 1 are 192.168.1.10. Finally, Client 1 receives DHCP information from DHCP server 1 because it comes first.
After Client 1 request DHCP information successfully, the client 2 request. In this situation, DHCP information packet of DHCP server 2 comes first with IP address 192.168.1.10.
So the Junos device will drop the packet or transfer to Client 2?
Thank all, 🙂
