RPR protection mode/static ringlet selection configuration

example

Network requirements

As shown in Figure 16, Stations A through E form an RPR ring and operate in steering protection mode

by default. Change the protection mode of the ring to wrapping. Configure a static ringlet selection entry

to allow frames from Station A to Station B to travel Ringlet 1 when no edge occurs on the RPR ring (that

is, the ring remains closed).

Configuration procedure

1. Configure the protection mode:

# Create RPR logical interface RPR 1 on Station A, and configure the protection mode as wrapping

on the interface.

<StationA> system-view

[StationA] interface rpr 1

[StationA-RPR1] rpr protect-mode wrap

Configure Station B through Station E in the same way Station A is configured. (Details not shown.)

2. Configure static ringlet selection:

# On RPR logical interface RPR 1 of Station A, configure transmitting frames destined for Station B

through Ringlet 1.

[StationA-RPR1] rpr static-rs 000f-e257-0002 ringlet1

[StationA-RPR1] quit

3. Verify the configuration:

# Display ring topology information on Station A.

[StationA] display rpr topology ring

Ring-level topology information on interface: RPR1

Stations on ringlet0: 4

Stations on ringlet1: 4

Total stations on ring: 5

Jumbo preference: regular

Ring topology type: closed ring
