Cisco NX-OS: VXLAN and External Connectivity
How to connect VXLAN fabrics to the outside world — external routing, VRF leaking, and border leaf design.
Cisco NX-OS: VXLAN - vPC - Anycast
The problem with VXLAN and vPC — and how anycast VTEP solves it by presenting a single logical VTEP address.
Cisco NX-OS: VXLAN Symmetric Routing
EVPN IRB symmetric routing: how it solves the ARP/CAM scaling problems of asymmetric routing using L3 VNIs.
Cisco NX-OS: VXLAN Asymmetric Routing
EVPN IRB asymmetric routing: how it works, its limitations with ARP cache and CAM table scaling, and when to avoid it.
Cisco NX-OS: VXLAN BGP EVPN control plane
BGP EVPN as a control plane for VXLAN: route types, MP-BGP, and how it replaces flood-and-learn.
Cisco NX-OS: VXLAN Multicast Control Plane
Configuring VXLAN with multicast flood-and-learn control plane on Cisco NX-OS. Step-by-step with commands.
Cisco NS-OS: Virtual eXtensible LAN (VXLAN) Overview
VXLAN is a tunneling protocol that encapsulates Layer 2 Ethernet frames in Layer 3 UDP packets. An overview of how it works and why it exists.
Cisco NX-OS: FabricPath (FP)
FabricPath is Cisco's L2 routing technology — MAC-in-MAC routing that removes STP from the topology. How it works and when to use it.
Cisco NX-OS: vPC & Failures
How vPC handles failures: orphan ports, peer link loss, keepalive loss, and dual-active scenarios.
Cisco NX-OS: vPC & FHRP
FHRP acts as active/active forwarding over vPC. How HSRP and VRRP integrate with vPC on Nexus switches.
