Gentleman , finally I manage to handle two shared networks from two
relays.<br>
Now when my network grows and need more ip allocations I just will
add subnets to each shared network declaration.<br>
Te scenario would be:<br>
<img alt="rel" title="rel"
src="cid:part1.00060704.07000607@gmail.com" width="559"
height="264"><br>
<br>
Te config is:<br>
<br>
shared-network Relay1 {<br>
subnet 192.168.88.0 netmask 255.255.255.128 {<br>
range 192.168.88.2 192.168.88.126;<br>
option broadcast-address 192.168.88.127;<br>
option subnet-mask 255.255.255.128;<br>
option routers 192.168.88.1;<br>
<br>
}<br>
subnet 192.168.89.0 netmask 255.255.255.128{<br>
range 192.168.89.2 192.168.89.126;<br>
option broadcast-address 192.168.89.127;<br>
option subnet-mask 255.255.255.128;<br>
option routers 192.168.89.1;<br>
}<br>
}<br>
<br>
shared-network Relay2 {<br>
subnet 192.168.88.128 netmask 255.255.255.128 {<br>
range 192.168.88.130 192.168.88.254;<br>
option broadcast-address 192.168.88.255;<br>
option subnet-mask 255.255.255.128;<br>
option routers 192.168.88.129;<br>
}<br>
<br>
subnet 192.168.89.128 netmask 255.255.255.128 {<br>
range 192.168.89.130 192.168.89.254;<br>
option broadcast-address 192.168.89.255;<br>
option subnet-mask 255.255.255.128;<br>
option routers 192.168.89.129;<br>
}<br>
}<br>
Next; I will add a failover pair and test it<br>
<br>
Btw; I would like to add that my escenario has been simulated using
virtualbox with two centos and a pfsense VM.<br>
Also used two very usefull tools : dhcpd-pools to check in real time
how the leases are being consumed , and dhcperf to simulate the dhcp
requests.<br>
If somebody want to get help about compile / use them or any info
related to virtualbox networking setting , please let me know.<br>
I got a lot of help from this list, I would like also to share
something back.<br>
<br>
Regards.<br>
Leandro.<br>

<div>Besides the remarks you already got on shared networks, in
the configuration of pool#2 you define in option routers the
first IP address(129) of the range.</div>
<div>It will not solve your problem, but I suggest you start the
range at 130.</div>

<div bgcolor="#FFFFFF" text="#000000">Hi guys , while trying
to get my config working, got this unexpected result.<br>
After setting following connection diagram:<br>

<br>
Having following dhcpd.conf subnet config:<br>
<br>
shared-network Public {<br>
subnet 192.168.88.0 netmask 255.255.255.0{<br>
#pool1<br>
pool{<br>
range 192.168.88.2 192.168.88.126;<br>
option broadcast-address 192.168.88.127;<br>
option subnet-mask 255.255.255.128;<br>
option routers 192.168.88.1;<br>
}<br>
#pool2<br>
pool{<br>
range 192.168.88.129 192.168.88.254;<br>
option broadcast-address 192.168.88.255;<br>
option subnet-mask 255.255.255.128;<br>
option routers 192.168.88.129;<br>
}<br>
<br>
}<br>
<br>
}<br>
<br>
<br>
I got following lease asigment:<br>
Jun 29 17:04:42 centos86_64 dhcpd: DHCPDISCOVER from
08:00:27:95:d9:62 via 192.168.88.129<br>
Jun 29 17:04:42 centos86_64 dhcpd: DHCPOFFER on
192.168.88.33 to 08:00:27:95:d9:62 via 192.168.88.129<br>
Jun 29 17:04:42 centos86_64 dhcpd: DHCPREQUEST for
192.168.88.33 (20.1.1.254) from 08:00:27:95:d9:62 via
192.168.88.129<br>
Jun 29 17:04:42 centos86_64 dhcpd: DHCPACK on 192.168.88.33
to 08:00:27:95:d9:62 via 192.168.88.129<br>
<br>
What is wrong ?I expeted that request coming from
192.168.88.129 would receive some lease from pool2 since
192.168.88.129 falls there.<br>
Instead I, receibing a lease from pool1 including the router
option ... The client connected behind relay2 will never go
out.<br>
Any Ideas ?<br>
<br>
Thanks in advance,<br>
Leandro.<br>
