VCF fabric topology
In a VCF fabric, a device has one of the following roles:
Spine node—Connects to leaf nodes.
Leaf node—As shown in Figure 103, a leaf node connects to a server in a typical data center network. A shown in Figure 104, a leaf node connects to an access node in a typical campus network.
Access node—Connects to an upstream leaf node and downstream terminal devices. Only the access device can be an access node.
Border node—Located at the border of a VCF fabric to provide access to the external network.
Spine nodes and leaf nodes form a large Layer 2 network, which can be a VLAN, a VXLAN with a centralized IP gateway, or a VXLAN with distributed gateways. For more information about centralized IP gateways and distributed IP gateways, see VXLAN Configuration Guide.
