To configure the RPR protection reversion mode on the RPR station:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter RPR logical interface
view.
interface rpr interface-number N/A
3. Configure the protection
reversion mode.
rpr reversion-mode { revertive |
non-revertive } Optional.
Revertive mode applies by default.
Manually sending a protection request
You can send FS or MS protection requests to trigger protection switchover or send idle protection
requests to clear manually sent protection requests on the RPR station.
To send a protection request:
Step Command
1. Enter system view. system-view
2. Enter RPR logical interface view. interface rpr interface-number
3. Send an RPR protection request on a ringlet.
rpr admin-request { fs | ms | idle } { ringlet0 |
ringlet1 }
Configuring the ringlet selection table
Each RPR station maintains a ringlet selection table for making ringlet selection decisions for frame
transmission. A ringlet selection table entry contains such information as the MAC address of a station,
the ringlet through which frames are transmitted.
The following are supported RPR ringlet selection tables:
• Static ringlet selection table is administratively configured to specify the ringlet for delivering a
frame to a destination station.
• Dynamic ringlet selection table is built dynamically based on the topology database, also known as
“shortest path ringlet selection table.”
• Default ringlet selection table specifies the default ringlet for delivering frames.
• Overall ringlet selection table is created from the above three tables. In the case of closed ringlets,
static ringlet selection table has the highest priority. If a static ringlet selection entry is available for
reaching a destination station, it is added into the overall ringlet selection table. If no static entry is
available, the system looks at the dynamic ringlet selection table. If two shortest paths are available,
default ringlet selection applies to pick up one from them. The selected entry is then added into the
overall ringlet selection table. When sending frames, the station consults this table to identify the
path to the destination MAC address. In the case of open ringlets, the overall ringlet selection table
can be created from only the dynamic ringlet selection table.
Adding a static ringlet selection entry
To add an entry to the static ringlet selection table:
