5. Core Layer
5.4 Core Layer Configuration Details
The following sections provide configuration information for the VENA Data Center solution core layer.
The core layer will be used to verify data center operations over an IEEE 802.1aq Shortest Path Bridging (SPB) core. One series of tests will have an SPB core using the Avaya VSP 9000 running Release 3.3 software. Another series of tests will have an SPB core using the ERS 8800 series switches running Release 7.1.3.
The IEEE ratified the 802.1aq standard that defines SPB and the Type-Length-Value (TLV) encoding that IS-IS uses to support SPB services. With Release 7.1.3, Avaya is in full compliance with the IEEE 802.1aq standard.
5.4.1 Virtual LANs and IP Subnets
The SBPB core terminates the data center and access layer VLANs on the BEB switch cluster switches.
Depending on the SPB topology being evaluated, the VLANs are either terminated and routed by the BEB switches or transported through the core using MAC-in-MAC encapsulation. To create the SPB core, two backbone VLANs (B-VLAN) will be created.
The following table provides an example of the VLAN IDs and IP subnet schemes which can be deployed:
