Enabling TRILL distribution tree multithread calculation
IMPORTANT:
This feature is available in Release 1138P01 and later versions.
This feature enables a multicore CPU device to improve TRILL distribution tree calculation efficiency
by using each thread to calculate a distribution tree.

Enabling load balancing over TRILL distribution trees
IMPORTANT:
This feature is available in Release 1138P01 and later versions.
By default, ingress traffic is not load balanced over TRILL distribution trees after a forwarding VLAN
is deleted on the RB. To load balance ingress traffic of the remaining forwarding VLANs over the
existing distribution trees, you can enable load balancing over TRILL distribution trees.
Ingress traffic is load balanced in any of the following conditions, regardless of whether load
balancing is enabled or not:
•
A forwarding VLAN is added.
•
A distribution tree is added or deleted.
When a distribution tree is added, the RB switches ingress traffic to the new tree to implement load
balancing. However, the RB cannot use the new distribution tree to forward traffic before other RBs
are ready to use the new tree. In this case, you can set a delay timer for the RB to switch ingress
traffic to the new distribution tree.
If traffic is not evenly distributed over distribution trees, you can also perform one-time load balancing
over TRILL distribution trees.
To enable load balancing over TRILL distribution trees:
