The following checklist is to configure LLT over UDP:

• Make sure that the LLT private links are on separate subnets. Set the broadcast address in /etc/llttab explicitly depending on the subnet for each link.

• Make sure that each NIC has an IP address that is configured before configuring LLT.

• Make sure the IP addresses in the /etc/llttab files are consistent with the IP addresses of the network interfaces.

• Make sure that each link has a unique not well-known UDP port.

• Set the broadcast address correctly for direct-attached (non-routed) links.

• For the links that cross an IP router, disable broadcast features and specify the IP address of each link manually in the /etc/llttab file.
