Load-balanced intersecting-ring configuration example
Network requirements
As shown in Figure 23:
Device A, Device B, Device C, Device D, and Device F form RRPP domain 1. 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 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.
Device A, Device B, Device C, Device D, and Device E form RRPP domain 2. 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 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.
Specify VLAN 11 as the protected VLAN of domain 1, and VLAN 12 the protected VLAN of domain 2. You can implement VLAN-based load balancing on Ring 1.
Ring 2 and Ring 3 have the same edge node and assistant edge node, and the two subrings have the same SRPTs. You can add Ring 2 and Ring 3 to an RRPP ring group to reduce Edge-Hello traffic.
