JUNOS 10.1 Network Interfaces Configuration Guide
Node ID
For each node in the ring, a unique node ID identifies each node. The node ID is the
node's MAC address. You can configure this node ID when configuring the ring on
the node or automatically select an ID such as STP. In most cases, you will not
configure this and the router will select a node ID, like STP does. It should be the
manufacturing MAC address. The ring node ID should not be changed, even if you
change the manufacturing MAC address. Any MAC address can be used if you make
sure each node in the ring has a different node ID.
Bridge Domains with the Ring Port
From the router point of view, the protection group is seen as an abstract logical port
that can be configured to any bridge domain. Therefore, if you configure one ring
port or its logical interface in a bridge domain; you must configure the other related
ring port or its logical interface to the same bridge domain. The bridge domain that
includes the ring port acts as any other bridge domain and supports the IRB layer 3
interface.
Configuring Ethernet Ring Protection Switching
The inheritance model follows:
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 (
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.
