Welcome to the STORDIS GNS3 SONiC DataCenter Release Notes.

This article describes the GNS3 SONiC DataCenter 2.2.0 L2/L3 EVPN lab scenario. The scenario contains configurations for two spine switches, three leaf switches and one multihomed SONiC host, targeting Broadcom Enterprise SONiC 4.6.0 virtual switches.

The newest release is listed first. The previous 2.1.0 entry remains below for reference.

GNS3 SONiC DataCenter 2.2.0

Release date: dd/mm/yyyy

Release summary

This release adds a lab scenario for Layer 2 connectivity over EVPN/VXLAN, inter-subnet routing in a tenant VRF over L3 EVPN/VXLAN, and EVPN multihoming. The supplied CLI files configure an eBGP IPv4 underlay and an EVPN control plane across two spine and three leaf switches.

New lab scenarios and configuration

• Layer 2 EVPN/VXLAN: LEAF-1 and LEAF-2 extend VLAN 11 through L2VNI 10011 for two hosts in the 10.10.11.0/24 subnet. VLAN 10 uses L2VNI 10010 for the multihomed host. LEAF-3 maps VLAN 20 to L2VNI 10020.

• Layer 3 EVPN/VXLAN: The three leaf switches configure Vrf-lab with L3VNI 50000 and anycast gateways. The lab includes a routed traffic scenario between a host in 10.10.11.0/24 and a host in 10.10.20.0/24.

• EVPN multihoming: LEAF-1 and LEAF-2 configure an Ethernet segment on PortChannel1 for the dual-attached MH-host. The CLI files also configure EVPN multihoming startup delay and uplink link-state tracking.

• Underlay and overlay: Each leaf peers with both spine switches using eBGP for IPv4 unicast reachability and L2VPN EVPN. Each leaf has its own VXLAN VTEP address.
