Basic VLAG Configuration

Figure 19 shows an example configuration where two VLAG peers are used for
aggregating traffic from downstream devices.

Client Switch
In this example, each client switch is connected to both VLAG peers. On each client
switch, the ports connecting to the VLAG peers are configured as a dynamic LACP
port LAG. The VLAG peer switches share a dedicated ISL for synchronizing VLAG
information. On the individual VLAG peers, each port leading to a specific client
switch (and part of the client switch's port LAG) is configured as a VLAG.
In the following example configuration, only the configuration for VLAG 1 on
VLAG Peer 1 is shown. VLAG Peer 2 and all other VLAGs are configured in a
similar fashion.
