Juniper IP Fabric EVPN-VXLAN

Install Gns3 on Windows, download the software and Gns3 VM, import the VM into VMware Workstation, and build a test with a switch and two PCs using 192.168.1.1/24 and 192.168.1.2/24.

Install and run the Gns3 VM on M-series Macs using UTM and access it via 192.168.64.9:80. Note limitations with 8 gb ram and 8 cpu cores on M1 MacBook Pro.

Install Gns3 on Ubuntu desktop by downloading the Linux package, installing the Gns3 GUI and server, and running it natively without the Gns3 VM.

Explore the IP fabric underlay, the physical infrastructure that routes overlay traffic and shares loopback addresses across devices using VXLAN and dynamic routing such as OSPF, ISIS, or BGP.

Map OSPF fundamentals, including link-state operation, the link-state database, and LSA exchanges, to form adjacencies and run Djikstra-based SPF. Learn single-area OSPF, DR/BDR roles, and basic troubleshooting.

Explore ISIS, a link-state routing protocol used in Juniper IP Fabric EVPN-VXLAN, including area concepts, backbone, level one and two routers, TLVs, PDUs, and adjacency troubleshooting.

Explore how BGP shares routing between autonomous systems, contrasts IBGP and EBGP, and uses next hop, AS path, origin, MED, and community to select the best paths.

Explore how BGP route reflectors concentrate routes from clients, advertise to other reflectors and peers, and use cluster list and originator ID to prevent loops.

Explore how overlay networks create a logical infrastructure atop the physical fabric, using iBGP/MP-BGP to carry evpn routes, vxlan tunnels, and ingress replication for multicast.

Explore how vxlan encapsulates layer 2 frames in layer 3 udp packets to extend vlans for vm infrastructure, using vni, vtep, and flood and learn with a multicast control plane.

Explore how vxlan mac learning works across vni networks, using vtep tunnels, flood and learn, arp discovery, and vxlan encapsulation to enable layer two data transfer between hosts.

Explore evpn, a vxlan data plane and control plane for mac learning that enables private layer 2 networks over ip, with multi-site connectivity and bgp-based learning.

Explore evpn components in vxlan deployments, including c devices, pe routers, leaf and spine roles, evpn instance (evi), ethernet segment es and esi, and underlay protocols.

Explore the five EVPN route types: type 1 ethernet auto discovery, type 2 mac ip advertisement, type 3 multicast, type 4 ethernet segment for multihoming, and type 5 inter-subnet routing.

Explore type one and type two evpn routes, including per api aliasing for active-active load balancing and mac mobility with sequence numbers and withdrawals.

Explore evpn bum traffic with type 3 and type 4 routes, and compare underlay multicast with ingress replication, including designated forwarders and split horizon for multihomed leaf switches.

Explore evpn implementation types and type five routes, from basic evpn with spine route reflectors to edge routed designs, enabling inter-vlan and data center routing via vtep tunnels.

Configure evpn-vxlan with an underlay ospf on spine and leaf, enable evpn signaling via internal bgp, set vtep, route-distinguisher, vrf target, and deploy vnis and routing instances on leaf switches.

Troubleshoot evpn vxlan by verifying underlay is up, loopbacks, overlay up, and vtep entries in the mac table; analyze evpn routes and use trace options or open a jtag case.

Configure the underlay for a Juniper EVPN-VXLAN lab using OSPF across spine and leaf switches, set loopbacks, verify neighbors and routes, and prepare for the overlay in the next lab.

Configure a Juniper IP Fabric EVPN-VXLAN overlay with BGP route reflectors, using underlay OSPF, VLANs and VXLANs, edge routed VPN configuration, and route distinguishers for routing.

Configure centrally routed EVPN-VXLAN topology by moving routing from leaf devices to spine devices, apply VLAN, VXLAN, and EVPN configurations on spines, and validate connectivity with ping.

Learn how edge-routed evpn with anycast gateways isolates vlans in a juniper ip fabric evpn-vxlan network, by configuring identical irb addresses and separate routing instances for vlans 10/20 and 30.

configure a centrally routed evpn with route leaking between vlan vrfs on spine devices, building vrf routing instances for vlan 10, 20, 30, and using route targets, import/export, and policies.

Configure edge routed evpn-vxlan with type 5 routes by creating routing instances for vlan 10, 20, and 30, and implement vpn export and import policies.
