Configuration Overview

This section provides an overview of the configuration. The configuration is done from the leader leader in clustering node relationship (formerly master) in the cluster. Follow this configuration sequence to prevent loops.

This configuration connects nodes using multiple paths. For an example of the configuration, refer to the following figure.

The configuration steps are as follows:

■

Configure stack GigaStream. The stack GigaStream connect the spine and leaf nodes. In the following figure, the stack GigaStream are: a1, a2, a3, b1, b2, b3, c1, c2, d1, d2, e1, e2. Even if there is only one port that connects the nodes, you must still configure a stack GigaStream. With a configuration of two spine nodes and three leaf nodes, the number of stack GigaStream is 12.

■

Configure spine links. On each leaf node, there is one spine link that contains the list of GigaStream connecting the leaf nodes to the spine nodes. The spine links contain multiple stack GigaStream that are bundled together. The spine links are: {c1,c2}, {d1,d2}, and {e1,e2}. The total number of spine links is three for this configuration. The spine links are located at the leaf nodes. Across the spine link members, traffic is load balanced. For this part of the configuration, refer to the circles in the following figure.

Note:  For the spine links, make sure that all paths are reachable.

■

Configure stack links. The stack links are: {a1,c1}, {a2,d1}, {a3,e1}, {b1,c2}, {b2, d2}, and {b3, e2}. The total number of stack links is six for this configuration. For this part of the configuration, refer to the circles in the following figure.

These configuration steps ensure that the spine and leaf nodes are fully meshed.
