3-11Configuring Control VLANsBefore configuring RRPP rings in an RRPP domain, configure the same control VLANs for all nodes inthe RRPP domain first.Perform this configuration on all nodes in the RRPP domain to be configured.Follow these steps to configure control VLANs:To do… Use the command… RemarksEnter system view system-view —Enter RRPP domain view rrpp domain domain-id —Specify the primary controlVLAN for the RRPP domain control-vlan vlan-id Requiredz To ensure proper forwarding of RRPPDUs, do not enable QinQ or VLAN mapping on the controlVLANs.z To ensure that RRPPDUs can be sent and received correctly, do not configure the default VLANof a port accessing an RRPP ring as the primary control VLAN or the secondary control VLAN.z To transparently transmit RRPPDUs on a device not configured with RRPP, you must ensure onlythe two ports connecting the device to the RRPP ring permit the packets of the control VLANs.Otherwise, the packets from other VLANs may go into the control VLANs in transparenttransmission mode and strike the RRPP ring.Configuring Protected VLANsBefore configuring RRPP rings in an RRPP domain, configure the same protected VLANs for all nodesin the RRPP domain first. All VLANs that the RRPP ports are assigned to should be protected by theRRPP domains. Perform this configuration on all nodes in the RRPP domain to be configured.Follow these steps to configure protected VLANs:To do… Use the command… RemarksEnter system view system-view —Enter RRPP domain view rrpp domain domain-id —Configure protected VLANs forthe RRPP domainprotected-vlanreference-instanceinstance-id-listRequiredBy default, no protected VLAN isconfigured for an RRPP domain.When configuring load balancing, ensure that the protected VLANs configured for different RRPPdomains are different.
