Configuring Multiple NIC Setup<br />
Overview When connecting to the MDP platform, customers can set up their <strong>CME</strong> <strong>Gateway</strong><br />
so that multiple NICs (two or more) face the <strong>CME</strong> Group’s network. Using this<br />
physical setup, customers can then route MDP feeds over specific NIC IP<br />
addresses.<br />
By default the fast.cfg file splits each channel into two feeds: A and B, which is<br />
ideal for two <strong>CME</strong> Group-facing NICs (one to support Feed A and the other to<br />
support Feed B). However, you must edit the file if you:<br />
• Use more than two <strong>CME</strong> Group-facing NICs, and thus want to create more<br />
than two MDP feeds<br />
• Want to maintain two feeds but name them something other than A and B.<br />

To route MDP Feeds using multiple <strong>CME</strong> Group-Facing NICs:<br />
1. Identify <strong>CME</strong> Group-facing NIC IP Addresses.<br />
2. Create a unique label (e.g., A, B, C, D) for each NIC IP address.<br />
3. Using Notepad, open hostinfo.cfg located in :\tt\config.<br />
4. In the [price_session] section, on a unique line, configure<br />
NetworkInterfaceFeed*=IP<br />
Where:<br />
• * is the unique label you assigned the IP address. If you only use two <strong>CME</strong><br />
Group-facing NICs, assign the first parameter A and the second parameter<br />
B.<br />
• IP is the IP address of the NIC through which you want to assign one or<br />
more MDP feeds<br />
5. Repeat Step 4 for each <strong>CME</strong> Group-facing NIC.<br />
6. If you only use two NICs and use feed labels A and B, stop this procedure;<br />
otherwise, continue to the next step.<br />
7. If you have more than 2 <strong>CME</strong> Group-facing NICs, or want to use feed labels<br />
other than A and B, using Notepad, open the fast.cfg located in :\tt\config.<br />
8. In each [fastInterface] section, edit the AddressFeed* parameters to<br />
include the new feed labels that you created.<br />
Including the feed label in parameter name routes that feed through the<br />
network interface assigned to that feed in Step 4.<br />
To use two <strong>CME</strong> Group-facing NICs with the addresses 10.2.2.3 and 10.2.2.4,<br />
open HostInfo.cfg and configure the following two parameters in the<br />
[price_session] section:<br />
NetworkInterfaceFeedA=10.2.2.3<br />
NetworkInterfaceFeedB=10.2.2.4<br />
The <strong>TT</strong> <strong>Gateway</strong> routes through the NIC with IP address 10.2.2.3 all data received<br />
from IP addresses listed in AddressFeedA in fast.cfg. The <strong>TT</strong> <strong>Gateway</strong> routes<br />
through the NIC with IP address 10.2.2.4 all data received from IP addresses<br />
listed in AddressFeedB in fast.cfg.<br />
The following diagram illustrates a setup that includes two <strong>CME</strong> Group-facing NICs<br />
and how the <strong>TT</strong> <strong>Gateway</strong> routes data based upon the contents of hostinfo.cfg<br />
and fast.cfg.
