When configuring load balancing, ensure that the protected VLANs configured for different
RRPP domains are different.
Configuring RRPP Rings
When configuring an RRPP ring, you must make some configurations on the ports connecting
each node to the RRPP ring before configuring the nodes.
z RRPP ports, that is, ports connecting devices to an RRPP ring, must be Layer-2 Ethernet
ports, Layer-2 GE ports, Layer-2 XGE ports, or Layer-2 aggregate interfaces and cannot be
member ports of any aggregation group, service loopback group, or smart link group.
z After configuring a Layer-2 aggregate interface as an RRPP port, you can still assign ports
to or remove ports from the aggregation group corresponding to the interface.
Configuring RRPP Ports
Perform this configuration on each node’s ports intended for accessing RRPP rings.
Follow these steps to configure RRPP ports:
To do… Use the command… Remarks
