## Source excerpt

Shipping netlab release 1.9.0 included running 36 hours of integration tests, including fifteen VXLAN/EVPN tests covering: Bridging multiple VLANs Asymmetric IRB, symmetric IRB, central routing, and running OSPF within an IRB VRF. Layer-3 only VPN, including routing protocols (OSPF and BGP) between PE-router and CE-routers All designs evangelized by the vendors: IBGP+OSPF, EBGP-only (including reusing BGP AS number on leaves), EBGP over the interface (unnumbered) BGP sessions, IBGP-over-EBGP, and EBGP-over-EBGP. All tests included one or two devices under test and one or more FRR containers1 running EVPN/VXLAN with the devices under test. The results were phenomenal; apart from a few exceptions, everything Just Worked™. Read more ...
