| Description | A lab to demonstrate EVPN over VXLAN on Nokia SR OS with containerlab |
| Components | Nokia SR OS, Multitool Alpine Linux |
| Resource requirements | N/A |
| Topology file | sros-ev-vxlan.clab.yml |
| Name | sros-ev-vxlan |
| Version information | containerlab:0.54.2, vr-sros:23.10.R1, docker-ce:24.0.5 |
The lab has Nokia SR OS connected in a Clos topology: two nodes as Spine and three nodes as Leaf, all with management interfaces also connected to the containerlab docker network. The Nokia SR OS VM is launched as a container using vrnetlab integration. The configuration uses iBGP as the underlay, with the reachability of each neighbor via OSPF; the overlay runs EVPN over VXLAN, and BUM handling is handled via ingress replication. BUM handling is handled through Ingress Replication. Other settings include BFD and ECMP. CE1 and CE2 are assigned to VLAN 10, CE3 and CE4 are assigned to VLAN 20, and there is no interconnectivity between VLAN 10 and VLAN 20.
- Topology: Clos
- Underlay: iBGP with OSPF
- Overlay: EVPN over VXLAN
- BUM: Ingress Replication
- Others: BFD, ECMP
- Client: VLAN10, VLAN20
This lab allows you to launch a basic interoperability scenario for a multi-tenant environment on EVPN over VXLAN using the Nokia SR OS. The lab directory contains the basic configuration files used to start the interoperability demonstration.
