Underlay
eBGP or OSPF underlay with ECMP, unnumbered links where supported, BFD everywhere.
Datacenter
The spine your network runs on.
VXLAN EVPN spine-leaf fabrics on Juniper, Cisco and Arista: BGP underlay, EVPN overlay, multihoming, anycast gateways and VRF segmentation — designed, proven on the twin, built and handed over as code.
What's included
01
02
EVPN overlay
Route types, RTs and RDs planned; symmetric IRB; anycast gateway; ARP suppression.
03
Multihoming
EVPN-ESI (or MLAG/vPC where the platform prefers) with all-active forwarding and tested failover.
04
Segmentation
Tenant VRFs, VNIs and route leaking designed with the security team; firewall insertion at border leaves.
05
Interconnect
DCI with EVPN Type-5, VXLAN stitching or EVPN-VXLAN over the WAN; cloud on-ramps.
06
Management
Apstra, Nexus Dashboard or CloudVision as the intent layer, driven from the repository.
How an engagement runs
01
Design
Topology, addressing, overlay and segmentation; BOM.
02
Twin
Fabric built virtually; failure and reachability tests passed.
03
Build
Rack, cable, certify, deploy from code.
04
Migrate and operate
Workloads moved in waves; live health portal on from day one.
Questions we get asked
Juniper, Cisco or Arista?
All three are first-class for us. The choice usually follows your team's skills, existing support contracts and whether you want Apstra's multi-vendor intent layer, ACI's policy model or CloudVision's operational tooling.
How big a fabric?
From two spines and four leaves to multi-pod fabrics with super-spines. The design method is the same.
