Example: Deploying DRNI and RDMA
Network configuration
As shown in Figure 1, build a Layer 2 network within the data center to implement traffic forwarding
across leaf devices and spine devices.
The following is the network configuration:
•
Deploy the leaf devices as access switches. Use DRNI to build two pairs of access switches as
DR systems. The DR interfaces in a DR system form a multichassis aggregate link for
improved link usage. Configure dual-active-gateway or VRRP for the leaf devices to provide
connectivity for servers.
•
Deploy the spine devices as aggregation switches. Configure them as route reflectors (RRs) to
reflect BGP routes among leaf devices.
•
Configure intelligent lossless network features such as PFC and data buffer to provide zero
packet loss for RDMA. In this example, zero packet loss is implemented for packets with
802.1p priority 3.
•
Configure DHCP relay on leaf devices to help servers obtain IP addresses.

Restrictions and guidelines
Determine the appropriate convergence ratio according to actual business needs. As a best
practice, use two or four high-speed interfaces for the IPL to meet the east-west traffic forwarding
requirements among servers in the same leaf group. Use other high-speed interfaces as uplink
interfaces. Use common-rate interfaces to connect to servers. If the convergence ratio cannot meet
requirements, attach less servers to leaf devices.
When you enable PFC for an 802.1p priority, the device will set a default value for each threshold.
As a best practice, use the default threshold values. For more information, see "Tuning the
parameters" and "Guidelines for tuning parameters."
You can configure WRED by using one of the following approaches:
•
Interface configuration—Configure WRED parameters on an interface and enable WRED.
You can configure WRED parameters for only the RoCE queue. You can configure WRED
parameters on different interfaces. This approach is recommended.
•
WRED table configuration—Create a WRED table, configure WRED parameters for a queue,
and then apply the WRED table to an interface. If you do not configure WRED parameters for a
queue, the default values are used for that queue. As a best practice, configure WRED
parameters for each queue because the default values are small and might not be applicable.
Configuring 5945 switches as leaf nodes
This example describes the procedure to deploy nodes Leaf 1 and Leaf 2. The same procedure
applies to nodes Leaf 3 and Leaf 4 except the single-homed device configuration.

Configuring priority mapping
NOTE:
•
To configure PFC on an interface connecting a leaf device to a server, you must configure the
interface to trust the 802.1p or DSCP priority in packets. To configure PFC on a Layer 3
interface connecting a leaf device to a spine device, you must configure the interface to trust the
DSCP priority in packets.
•
As a best practice, configure outgoing packets of servers to carry the DSCP priority and to be
enqueued by DSCP priority. In this case, configure the interface connecting a leaf device to a
server to trust the DSCP priority in packets. If the server does not support carrying the DSCP
priority, configure the interface connecting a leaf device to a server to trust the 802.
1p priority in
packets and configure DSCP-to-802.1p mappings for all involved packets.
•
This section describes the procedure to configure DSCP-to-
802.1p mappings when an interface
is configured to trust 802.1p priority in packets. This section does not need
to be configured if an
interface is configured to trust the DSCP priority in packets.
