<tt>Beware of one pitfall that I found the hard way:<br>
<br>
interface ve 10<br>
ip address 192.168.0.1 255.255.255.0<br>
ip address 10.20.30.1 255.255.255.0<br>
ip helper-address 1 172.16.0.1<br>
!<br>
<br>
In the above configuration ALL of your IP addresses issued using DHCP
will come from the 10.20.30.0/24 network, even if you want the other
network to be the "primary" network for DHCP. According to Foundry
support techs, "This is because When the Layer 3 Switch forwards a
BootP/DHCP request, the Switch “stamps” the Gateway Address field. The
default value the Layer 3 Switch uses to stamp the packet is the
lowest-numbered IP address (10.20.30.1) configured on the interface
that received the request. Changing this will make your DHCP work."<br>
<br>
The command referenced is:<br>
ip bootp-gateway 192.168.0.1<br>
<br>
The final config would look like:<br>
</tt><tt>interface ve 10<br>
ip address 192.168.0.1 255.255.255.0<br>
ip address 10.20.30.1 255.255.255.0<br>
ip helper-address 1 172.16.0.1<br>
</tt><tt>ip bootp-gateway 192.168.0.1</tt><br>

<div style="margin: 0px;">On a Foundry the term "secondary ip
address" refers to a second IP address on the SAME SUBNET as the
primary address. Very different from the Cisco definition.</div>
<div style="margin: 0px;"><br class="webkit-block-placeholder">
</div>
<div style="margin: 0px;">To put a second IP on a different subnet,
simply specify another "ip address" clause without the "secondary"
keyword, and it should work fine.</div>
