You can deploy RRPP only after basic functions of RRPP are configured. If RRPP is deployed with VPLS, you need to configure RRPP snooping. Table 1 describes the RRPP configuration tasks.

Configure RRPP |
RRPP prevents loops when the ring is complete. RRPP can rapidly restore communication on the ring network when the ring network is faulty. There are three networking modes: single ring, intersectant ring, and tangent ring. |

Configure RRPP snooping NOTE:
Only the S5720-EI, S5720-HI, S5730-HI, S5731-H, S5731S-H, S5732-H, S6720-EI, S6720-HI, S6720S-EI, S6730S-H, and S6730-H support this function. |
RRPP snooping notifies a VPLS network of changes in an RRPP ring. After RRPP snooping is enabled on sub-interfaces or VLANIF interfaces, the VPLS network can transparently transmit RRPP packets, detect changes on the RRPP ring, and update forwarding entries, ensuring that traffic can be rapidly switched to a non-blocking path. |
