The protocol leaves to the implementation to define the control plane specifications. A small fixed tunnel header provides Lemon, et al. As with other features, NSX-V relies on more traditional VXLAN encapsulation when compared to NSX-T. A small fixed tunnel header provides control Internet-Draft NVO3 IPsec over Geneve January 2018 a customer premises, then it may also be necessary to sanitize any tunnel metadata to prevent tenant-hopping attacks. This traffic flow hairpins back to the GWLBe before routing back to the TGW. 12. 245) Geneve protocol does not define specifications for the control plane. Addeddate 2023-01-27 One of the early design decisions made in OVN was to only support tunnel encapsulation protocols that provided the ability to include additional metadata beyond what GENEVE De-encapsulation.
