TRILL configuration example
Network requirements
As shown in Figure 9, configure TRILL in the Layer 2 data center network as follows:
• Enable TRILL on the downlink ports of access layer devices to connect terminal devices to the TRILL
network.
• Enable TRILL on the uplink ports of access layer devices, and configure these uplink ports as trunk
ports to pass TRILL frames to the TRILL network.
• Enable TRILL on the downlink ports of distribution layer devices, and configure these downlink ports
as trunk ports to forward TRILL data frames.
• Enable TRILL on the uplink ports of the distribution layer devices. These ports send the
de-encapsulated TRILL data frames to the core layer.
• In the TRILL network, configure four TRILL distribution trees with RB 6 through RB 9 as the root bridges.
RB 6 through RB 9 are in descending priority order.
A hierarchical network has three layers (from up to down): the core layer, distribution layer, and access
layer. Usually, a port connecting to a higher layer device is called an uplink port, and a port connecting
to a lower layer device is called a downlink port.

Configuration procedure
This section provides only TRILL-related configurations.
1. Configure the downlink ports of access layer devices:
# Enable TRILL globally on RB 1, and enable TRILL on downlink port Ten-GigabitEthernet 1/0/1 of
RB 1.
