Campus Fabric
the translation of fabric context is generally 1:1. The Fabric Border Node is also the device where the fabric
control planes of two domains exchange reachability and policy information.
APIC-EM Controller : This is the SDN controller developed by the Enterprise Networking Group. This
controller serves both Brownfield and Greenfield deployments. Campus Fabric service will be developed on
the APIC-EM controller. This service will drive the management and orchestration of the Campus Fabric, as
well as the provision of policies for attached users and devices.
Fabric Header: Fabric header is the VXLAN header which carries the segment ID(VNI) and user group(SGT).
SGT is encoded in the reserved bits of the VXLAN header.
Cisco Catalyst 3000 is positioned as the fabric edge and Cisco Nexus 7700 is positioned as the fabric border
in this architecture. LISP is the control plane in the campus fabric architecture and it programs the VXLAN
routes. LISP is enhanced to support VXLAN routes for Campus Fabric architecture.
The following features are supported on Cisco Nexus 7700:
• LISP control plane pushing VXLAN routes
• VXLAN L3GW (VRF-lite Hand-off)
• Optimal Tenant L3 Multicast (ASM/Bidir/SSM) based on LISP Multicast (Ingress Replication over
unicast core)
• IS-IS as underlay
• TTL propagation
