Configuration Procedure - H3C S5830V2 Series Configuration Manual

•
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.
Configure the downlink ports of access layer devices:
1.
# Enable TRILL globally on RB 1, and enable TRILL on downlink port Ten-GigabitEthernet 1/0/1
of RB 1.
<RB1> system-view
[RB1] trill
[RB1-trill] quit
[RB1] interface ten-gigabitethernet 1/0/1
[RB1-Ten-GigabitEthernet1/0/1] trill enable
[RB1-Ten-GigabitEthernet1/0/1] quit
# Configure RB 2 through RB 5 in the same way RB 1 is configured. (Details not shown.)
Configure the uplink port of access layer devices:
2.
# Enable TRILL on uplink port Ten-GigabitEthernet 1/0/2 through Ten-GigabitEthernet 1/0/5 of
RB 1, and configure these ports as trunk ports.
