sample evpn lab

  • A baseline setup for EVPN L2 and L3 services made with Nokia SRL, using VXLAN transport.
  • Runs on containerlab , see the clab.yml file and edit as your scenario requires (e.g. Leaf&Spine or MH)
  • Router configurations are provided under the flat-config dir.

lab setup

Two Alpine nodes are connected to a four-nodes "core", internal cross-links can be added to mimic a leaf&spine setup.

the diagram shows the idea

the picture shows ethernet port connectivity and the underlay IGP setup

the diagram shows the idea

these are the services already provided in the configuration, a L2 point to point and a L3 EVPN-based service

the diagram shows the idea

wireshark pcap evpn_l2.pcap shows EVPN route-type 2 exchange

wireshark pcap evpn_l3.pcap shows EVPN route-type 5 exchange

the diagram shows the idea

client configuration

Just copy'n'paste to Alpine nodes to get reachability for L2/L3 services
