BOOTP Relay

[T_Pitch]

Hello,

I'm having trouble with PCs on VLAN 17 getting IP addresses from the DHCP server on VLAN 2. All of our PCs and our servers are on the same subnet, and I'm working on splitting those but want to keep just the one DHCP server. My requests are not being seen by my DHCP server, and I've gone through this troubleshooting article and everything looks good: https://extremeportal.force.com/ExtrArticleDetail?an=000081832

Layer 2 works because I've statically assigned an IP to a PC to test. I was able to traverse my entire network with a statically assigned address (even ping the DHCP server). I have even tried DHCP from my core switch, but it fails.

Running Wireshark I can see the broadcast leaving the PC, but never making it to my DHCP server. So I mirrored VLAN 2 to a port at my core and watched for that MAC address to show up just as the article above suggests in Case 2 step 7 in which I never saw a DHCP Discover come across.

TOPOLOGY
[ LAPTOP ] ----- [ SWITCH 2 ] -------- [ CORE SWITCH ] ------- [ VM Host ] ----- [ VM: DHCP SERVER ]

CORE CONFIGURATION:
configure bootprelay add 192.168.192.168 vr VR-Default
enable bootprelay ipv4 vlan 17
configure bootprelay vlan 17 add 192.168.192.168

I'm sure I've missed something obvious.

Hi T,

The bootprelay needs to be enabled on both the client and vlan where the DHCP server is located.

Thanks
