§Campus Fabric
CLI or API approach to build a LISP +
VXLAN + CTS Fabric overlay for your
enterprise Campus networks
CLI provides backwards compatibility
but management is box-by-box.
API provides device automation via
NETCONF/YANG
Separated management systems
APIC-EM

§SD-Access
GUI approach provides automation &
assurance of all Fabric configuration,
management and group-based policy

A Fabricis an Overlay
An Overlay network is a logical topologyused to virtually connect devices,
built on top of a simple physical Underlay network.
An Overlay network often uses alternate forwarding attributes to provide
additional services, not provided by the Underlay.

as the Fabric Underlay!
•Key Requirements
•IP reachfrom Edge to Edge/Border/CP
•Can be L2 or L3 –We recommend L3
•Can be any IGP–We recommend ISIS
•Key Considerations
•MTU (Fabric Header adds 50B)
•Latency (max RTT =/< 100ms)

Virtual Network–A Closer Look
Virtual Network maintains a separate Routing & Switching table for each instance
•Control-Plane uses Instance ID to maintain separate
VRF topologies (“Default” VRF is Instance ID “4098”)
•Nodes add a VNID to the Fabric encapsulation
•Endpoint ID prefixes (Host Pools) are routed and
advertised within a Virtual Network
•Uses standard “vrf definition” configuration, along
with RD & RT for remote advertisement (Border Node)

Scalable Groups –A Closer Look
Scalable Group is a logical policy object to “group” Users and/or Devices
•Nodes use “Scalable Groups” to ID and assign a
unique Scalable Group Tag (SGT) to Endpoints
•Nodes add a SGT to the Fabric encapsulation
•SGTs are used to manage address-independent
“Group-Based Policies”
•Edge or Border Nodes use SGT to enforce local
Scalable Group ACLs (SGACLs)

Host Pools –A Closer Look
Host Pool provides basic IP functions necessary for attached Endpoints
•Edge Nodes use a Switch Virtual Interface (SVI),
with IP Address /Mask, etc. per Host Pool
•Fabric uses Dynamic EID mapping to advertise each
Host Pool (per Instance ID)
•Fabric Dynamic EID allows Host-specific (/32, /128
or MAC) advertisement and mobility
•Host Pools can be assigned Dynamically (via Host
Authentication) and/or Statically (per port)

Anycast Gateway–A Closer Look
•Similar principle and behavior as HSRP / VRRP with
a shared “Virtual” IP and MAC address
•The same Switch Virtual Interface (SVI) is present
on EVERY Edge, with the same Virtual IP and MAC
•Control-Plane with Fabric Dynamic EID mapping
maintains the Host to Edge relationship
•When a Host moves from Edge 1 to Edge 2, it does
not need to change it’s Default Gateway J

SVI, and is then transferred by Fabric
•Fabric Dynamic EID mapping allows Host-specific

•Host 1 connected to Edge A can now use the same
IP subnet to communicate with Host 2 on Edge B
