ERP over ESI VLAN (Brocade NetIron CES and Brocade NetIron CER)
15
The interconnection nodes play a vital role in traffic forwarding and should be aware of ERP
instances associated with each other within the node. In
Figure 146 , the DUT17 interconnection
node needs to be aware of Ring 1 being a sub-ring of the Ring 2 ERP instance. This association is
important as it is required to perform a FDB flush in Ring-2 on receiving R-APS (SF) messages from
Ring-1 .
Interconnection Rings with same VLANs
The PBB case such as in Figure 147 , where one B-VLAN span across multiple rings, the ring
mapping will still be maintained as it helps push the events from sub-rings to major ring.
The PB case will be also handled similarly.
