Configure Switch Features Chapter 7
Figure 17 shows two Stratix 5700 switches that are configured as ring nodes
with redundant gateway:
• One switch is a ring node and the active redundant gateway.
• The other switch is a ring node and the backup redundant gateway.
In this example, the switch provides redundant gateway functionality, so that
all ring nodes have access to the outside network.
