TRILL configuration task list

When you configure TRILL, follow these guidelines:

•

Configuration in Layer 2 Ethernet interface view takes effect on only the current port. Configuration
in Layer 2 aggregate interface view takes effect on the current interface and its member ports.

Configuration on the member port of an aggregate interface takes effect after the member port

leaves the aggregation group.

•

When both TRILL and a spanning tree protocol are enabled on a port, TRILL processes the BPDUs

received on the port. To make sure the STP network can correctly interoperate with the TRILL network,
disable the spanning tree protocol on TRILL ports. For more information about spanning tree

protocols, see Layer 2—LAN Switching Configuration Guide.

•

H3C recommends not enabling loop detection on TRILL ports, because TRILL networks prevent loops
from being generated. For more information about loopback detection, see Layer 2—LAN

Switching Configuration Guide.

•

Do not configure the TPID for VLAN tags on RBs. For more information about TPIDs, see Layer 2
—

LAN Switching Configuration Guide.

•

Do not connect multiple TRILL ports on an RB to the same link. Otherwise, these TRILL ports might be
elected as the AVFs of a VLAN at the same time because these TRILL ports cannot sense each other.

As a result, loops will occur in the VLAN.
