Nokia SR OS EVPN over MPLS with LDP Lab

Items Description
Description A lab to demonstrate EVPN over MPLS on Nokia SR OS with containerlab
Components Nokia SR OS, Multitool Alpine Linux
Resource requirements N/A
Topology file sros-ev-mpls.clab.yml
Name sros-ev-mpls
Version information containerlab:0.54.2, vr-sros:23.10.R1, docker-ce:24.0.5

Description

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 MPLS, 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 MPLS with LDP
  • BUM: Ingress Replication
  • Others: BFD, ECMP
  • Client: VLAN10, VLAN20

Topology

Use cases

This lab allows you to launch a basic interoperability scenario for a multi-tenant environment on EVPN over MPLS using the Nokia SR OS. The lab directory contains the basic configuration files used to start the interoperability demonstration.
