i have the following network:
The lower right router shall be my dhcp server (net 192.168.2.0/24 - ip 192.168.2.3)
It shall provide IPs for the upper left and lower left PCs and Printers.
The lower left net: 192.168.1.0/24 The upper left: 192.168.0.0/24
I configured the ip helper-address 192.168.2.3 on the lower left routers for vlan 2 interface witch is the one connected to the switches
If i wireshark the connection i cann see the DHCP discover message reaching the router in the lower right. The problem is: i don't get a reply from the dhcp server.
This is the config of it:
ip dhcp excluded-address 192.168.1.1 192.168.1.30 ip dhcp pool area1 network 192.168.1.0 255.255.255.0 ! (192.168.1.2 is the vlan interface of the lower left router) default-router 192.168.1.2
EDIT// Just found out that my DHCP Server 'prentends' sending out dhcp offers ... but they never reach the client or even the next router as you can see on this wireshark snap:
And additionally if i enter 'show ip dhcp binding' the server did assign an ip (192.168.1.31) to the correct mac address .... but it just never reached the client
Another question: Is there a possibility to put the second interface of the dhcp server into the same subnet for redundancy reasons?
