R3303-HP HSR6800 Routers High Availability Configuration Guide

• Dynamic ringlet selection table—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—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.
• Virtual router redundancy protocol (VRRP) ringlet selection table—Saves the one-to-one map
between the virtual MAC address and real MAC address for each master VRRP station. The VRRP
ringlet selection table determines the ringlet for a frame whose destination address is a virtual MAC
address.

Command Remarks
1. Enter system view.

2. Enter RPR logical interface
view.
interface rpr interface-number N/A
3. Add a static ringlet selection
entry.
rpr static-rs mac-address { ringlet0
| ringlet1 }
No static ringlet selection entry is
created by default.
NOTE:
Static ringlet selection entries take effect only when the RPR ring is closed.
