Abstract:
TRILL uses distribution trees to deliver multi-destination frames.
Multiple trees can be used by an ingress RBridge for flows regardless
of the VLAN, Fine Grained Label (FGL), and/or multicast group of the
flow. Different ingress RBridges may choose different distribution
trees for TRILL Data packets in the same VLAN, FGL, and/or multicast
group. To avoid unnecessary link utilization, distribution trees
should be pruned based on VLAN and/or FGL and/or multicast
destination address. If any VLAN, FGL, or multicast group can be sent
on any tree, for typical fast path hardware, the amount of pruning
information is multiplied by the number of tree; however, there is a
limited capacity for such pruning information.
This document specifies an optional facility to restrict the TRILL
Data packets sent on particular distribution trees by VLAN, FGL,
and/or multicast group thus reducing the total amount of pruning
information so that it can more easily be accommodated by fast path
hardware.
