You can automatically configure LLT to use RDMA using the installer. To manually configure LLT over RDMA follow the steps that are given in this section.
The following checklist is to configure LLT over RDMA:
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 RDMA enabled NIC (RNIC) over an InfiniBand or Ethernet network has an IP address that is configured before configuring LLT.
Make sure that the IP addresses in the /etc/llttab files are consistent with the IP addresses of the network interfaces (InfiniBand or Ethernet network interfaces).
Make sure that each link has a unique and a private IP range for the UDP port.
See the sample comfiguration for direct-attached (non-routed) links.
