For each ring, a protection group must be configured. There may be several rings in each
node, so there should be multiple protection groups corresponding to the related Ethernet
rings.
Three interval parameters (restore-interval, guard-interval, and hold-interval) can be
configured at the protection group level. These configurations are global configurations
and apply to all Ethernet rings if the Ethernet ring doesn't have a more specific
configuration for these values. If no parameter is configured at the protection group level,
the global configuration of this parameter uses the default value.

This example uses the following hardware and software components:
• Router node 1 running Junos OS with two Gigabit Ethernet interfaces.
• Router node 2 running Junos OS with two Gigabit Ethernet interfaces.
• Router node 3 running Junos OS with two Gigabit Ethernet interfaces.
This section describes a configuration example for a three-node ring. The ring topology
is shown in Figure 35 on page 444.
