To connect a spanning tree network to a TRILL network, make sure the following requirements are
met:
{
The spanning tree protocol is disabled on the TRILL network.
{
An edge port is used to connect the spanning tree network to the TRILL network. The edge port
can quickly transit to the forwarding state. This prevents network topology changes from
influencing the TRILL network.
For more information about TRILL, see
TRILL Configuration Guide
.
•
The spanning tree configurations are mutually exclusive with service loopback and Smart Link.
•
Configurations made in system view take effect globally. Configurations made in Ethernet interface
view or WLAN mesh interface view take effect on the interface only. Configurations made in Layer
2 aggregate interface view take effect only on the aggregate interface. Configurations made on an
aggregation member port can take effect only after the port is removed from the aggregation
group.
•
After you enable a spanning tree protocol on a Layer 2 aggregate interface, the system performs
spanning tree calculation on the Layer 2 aggregate interface. It does not perform spanning tree
calculation on the aggregation member ports. The spanning tree protocol enable state and
forwarding state of each selected member port is consistent with those of the corresponding Layer
2 aggregate interface.
•
The member ports of an aggregation group do not participate in spanning tree calculation.
However, the ports still reserve their spanning tree configurations for participating in spanning tree
calculation after leaving the aggregation group.
