Go throught rhis lecture before you jump into eve-ng labs. I covered the issues i faced during the LAB
Explore the vxlan high-level overview, its open standard overlay over a layer three core, and how it avoids block ports and enables 16 million broadcast domains via vni.
Map a two-spine, three-leaf topology with simple spine-to-leaf IP schemes using 13.1.1.x and 24.1.1.x, and configure VLAN ten and VLAN twenty with VNI 1010 and 2020.
Explore static ingress replication in vxlan, configuring underlay ospf and vni ten (1010) with peer IPs, and discuss its ease of setup versus scalability limitations in large networks.
Explore packet flow with static ingress replication in a VXLAN environment, including ARP resolution, VLAN ten, VNI ten, and end-to-end encapsulation across leafs and spines.
Analyze how ingress replication with bgp evpn distributes vtep to vni mappings and trace a packet flow from host one to host five, detailing mac learning and vxlan headers.
Leverage multicast to enable intra-subnet host communication without BGP EVPN, using flood and learn with VNI multicast groups and PIM for underlay multicast.
Learn the multicast packet flow in a VXLAN network, including ARP learning and VXLAN encapsulation for VNI 1010 with multicast group 239 1010 from host one to host five.
Enable the suppress-arp feature to reduce broadcast in BGP EVPN by using the control plane to answer ARP requests, exchanging IP-to-MAC bindings via VNIs.
