Configuring Control VLANs
Before configuring RRPP rings in an RRPP domain, configure the same control VLANs for all nodes in
the 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...
Enter system view
Enter RRPP domain view
Specify the primary control
VLAN for the RRPP domain
To ensure proper forwarding of RRPPDUs, do not enable QinQ or VLAN mapping on the control
VLANs.
To ensure that RRPPDUs can be sent and received correctly, do not configure the default VLAN
of a port accessing an RRPP ring as the primary control VLAN or the secondary control VLAN.
To transparently transmit RRPPDUs on a device not configured with RRPP, you must ensure only
the 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 transparent
transmission mode and strike the RRPP ring.
Configuring Protected VLANs
Before configuring RRPP rings in an RRPP domain, configure the same protected VLANs for all nodes
in the RRPP domain first. All VLANs that the RRPP ports are assigned to should be protected by the
RRPP domains. Perform this configuration on all nodes in the RRPP domain to be configured.
Follow these steps to configure protected VLANs:
To do...
Enter system view
Enter RRPP domain view
Configure protected VLANs for
the RRPP domain
When configuring load balancing, ensure that the protected VLANs configured for different RRPP
domains are different.
Use the command...
system-view
rrpp domain domain-id
control-vlan vlan-id
Use the command...
system-view
rrpp domain domain-id
protected-vlan
reference-instance
instance-id-list
3-11
