6) Verification
After the configuration, you can use the display command to view RRPP configuration and
operational information on each device.
Intersecting-Ring Load Balancing Configuration Example
Networking requirements
z Device A, Device B, Device C, Device D, and Device F constitute RRPP domain 1, and
VLAN 100 is the primary control VLAN of the RRPP domain. Device A is the master node of
the primary ring Ring 1; Device D is the transit node of the primary ring Ring 1; Device F is
the master node of the subring Ring 3; Device C is the edge node of the subring Ring 3;
Device B is the assistant-edge node of the subring Ring 3.
z Device A, Device B, Device C, Device D, and Device E constitute RRPP domain 2, and
VLAN 105 is the primary control VLAN of the RRPP domain. Device A is the master node of
the primary ring Ring 1; Device D is the transit node of the primary ring Ring 1; Device E is
the master node of the subring Ring 2; Device C is the edge node of the subring Ring 2;
Device B is the assistant-edge node of the subring Ring 2.
z Specify VLAN 1 as the protected VLAN of domain 1, and VLAN 2 as the protected VLAN of
domain 2. Thus, you can achieve VLAN-based load balancing on the primary ring.
z As the edge node and assistant-edge node of subring Ring 2 is the same as those of
subring Ring 3, and the two subrings have the same SRPTs, you can add subrings Ring 2
and Ring 3 to the RRPP ring group to reduce Edge-Hello traffic.
