Help needed on DHCP relay

[ashok singh]

Hi All,
  
  I have configured DHCP server and relay agent as shown below. My DHCP  Server is giving error messages ( shown below ) when it receives DHCP  discover from the relay agent.Please help me out.
  
  
                          (eth0)
     +-------------+    10.0.0.1   +-------------+
  
     | DHCP Client  +---------------+ relay agent |
  
     +-------------+               +------+------+
  
                                           |   (eth0)
                                           | 192.168.0.8
                                           |
                                           |
                                           |   (eth0)
                                           | 192.168.0.1
  
                                     +-----+-------+
  
                                     | dhcp server |
  
                                     +-------------+
  
  
  my dhcpd.conf is as follows
  
  authoritative;
  ddns-update-style interim;
  ddns-updates off;
  omapi-port 7911;
  
  subnet 192.168.0.0 netmask 255.255.255.0 {
   option subnet-mask 255.255.255.0;
   range dynamic-bootp 192.168.0.30 192.168.0.49;
   option domain-name "test.com";
   default-lease-time 86400;
   max-lease-time 86400;
   min-lease-time 86400;
  }
  subnet 10.0.0.0 netmask 255.255.255.0 {
   option subnet-mask 255.255.255.0;
   range dynamic-bootp 10.0.0.30 10.0.0.49;
   }
  
  the dhcp server command line is "/usr/sbin/dhcpd eth0 -d"
  
  my relay agent command line is "/usr/sbin/dhcrelay -i eth0 -i eth1 -d 192.168.0.1"
  
  Since i have my dhcp server in debug mode i get the following messages 
  
  DHCPDISCOVER from <mac_address> via 10.0.0.1
  icmp_echorequest 10.0.0.49: Network is unreachable
  DHCPOFFER on 10.0.0.49 to <mac_address> via 10.0.0.1
  send_packet: Network is unreachable
  send_packet: please consult README file regarding broadcast address.
  
  At relay agent side i get the following messages
  
  forwarded BOOTREQUEST for <mac_address> to 192.168.0.1
  forwarded BOOTREQUEST for <mac_address> to 192.168.0.1
  forwarded BOOTREQUEST for <mac_address> to 192.168.0.1
  forwarded BOOTREQUEST for <mac_address> to 192.168.0.1
  
  I am using linux kernel 2.4.20-8 for both dhcp server and dhcp relay  agent. I am using ISC dhcp 3.0.3. I read the README file but didn't  help me much.
  
  I tried adding the following to my route table on DHCP Server
  "route add -host 255.255.255.255 dev eth0" but didn't help.
  
  Regards,
  Ashok
