Link aggregation fundamentals
If you disable distribution and a new port becomes active in a Multilink trunk, existing streams
remain on the original links. Enable distribution to redistribute the streams dynamically and
split the load on all the links of the MultiLink trunk. This redistributes a few streams at every
system time tick.
For a detailed description about the commands you use to configure multicast flow distribution
over MLT, see Avaya Ethernet Routing Switch 8800/8600 Configuration — IP Multicast Routing
Protocols, NN46205-501.
MLT network topology and configuration examples
The following reference information contains examples of MLT network topology and
configuration. The same topologies apply to MLT with LACP.
Example 1: Switch-to-switch MLT

trunks (T1 and T2) connecting switch S1 to switches S2 and S3.
Figure 1: Switch-to-switch MultiLink trunks configuration
In this example, you can configure each trunk with multiple switch ports to increase bandwidth
and redundancy. When traffic between switch-to-switch connections approaches single port
bandwidth limitations, you can create an MultiLink trunk to supply the additional bandwidth
required to improve performance, as well as providing physical link layer redundancy.
