DHCP for Inter-VLANs

[farrukh19911]

On PT it is working well, but on real network it isn'n working.

On real Network as a dhcp-relay, i have an 3750G Sw (Version 12.2(44) SE5, RELEASE SOFTWARE (fc1)

Ip routing is on.

All made as in the scheme, but i dont know why it didn't works.

Somebody can help me to solve this problem?

do you have the ip helper commands on the interface vlan 60 and 70

int vlan 60

ip helper-address 192.168.100.3

[farrukh19911]

Yes, ip helper-address 192.168.100.3 is also existing on vlans 60 and 70..

Packets reach the DHCP servers from the gateway VLAN 60 (20.1) with MAC address of VLAN 59, but do not go in a reply.

I put the log file.

Does the DHCP server work?

is there a scope for vlan 59? if not can you make one and test a client on vlan 59

or you could put the dhcp server on the switch

[farrukh19911]

When I appropriate a static IP for the host, it is working.

Even appears on the MikroTik dhcp server the host address and his name

I tested a client on vlan 59, it is working well.
