z Before specifying RRPP rings for an RRPP domain, you must specify protected VLANs for the
domain.
z Before specifying rings for an RRPP domain, you can delete or modify the protected VLANs
configured for the RRPP domain; after specifying rings for an RRPP domain, you can delete or
modify the protected VLANs configured for the RRPP domain, however, you cannot delete all the
protected VLANs configured for the domain.
z Deleting an RRPP domain deletes its protected VLANs at the same time.
z The protected-vlan command configures protected VLANs for an RRPP domain by referencing
MSTIs to which the protected VLANs are mapped. You can use the display stp
region-configuration command to view the VLAN-to-MSTI mappings. For detailed information
about VLAN-to-MSTI mapping configuration, refer to MSTP Configuration in the Access Volume.
z The control VLAN configured for an RRPP domain must be a new one.
z Control VLAN configuration is required for configuring an RRPP ring.
z A Ring ID cannot be applied to more than one RRPP ring in an RRPP domain.
z You must first configure the primary ring and then the subring when configuring an edge node.
Moreover, you must remove all subring configurations before deleting the primary ring
configuration of an edge node. However, the RRPP ring enabled cannot be deleted.
z To use the undo rrpp domain command to remove an RRPP domain, you must ensure the RRPP
domain has no RRPP ring.
z Before removing or modifying the control VLAN of an RRPP domain, make sure that the RRPP
domain is not configured with any RRPP ring.
Configuring Ring Group
To reduce Edge-Hello traffic, you can adopt the ring group mechanism, that is, assign subrings with the
same edge node/assistant-edge node to a ring group.
