The following table provides release information about the feature or features described in this module. Information for VxLAN GPE Tunnel and VxLAN Dummy-L2 Tunnel UDP source port hash uses 3 tuples for fragments, and 5 tuples for non-fragments. Provides facility to manually configure source port range for GPE tunnel and a Dummy-L2 tunnel.ģ-tuple hash is enabled to generate UDP source port for both VxLAN GPE and VxLAN Dummy-L2 tunnels for all the packets. Overlay encapsulation is supported for both IPv4 and IPv6, whereas underlay encapsulation is supported only for IPv4.ĨK Tunnel interfaces with VxLAN GPE or VxLAN dummy-L2 mode are supported.īoth VxLAN-GPE and VxLAN Dummy-2 are point to point tunnels. Leverages VxLAN-GPE draft-IETF, which provides direct upper layer protocols options such as, IPv4, IPv6, Ethernet (MAC), Network-Service-Header Port based on the inner IP protocol, source or destination IP addresses and L4 port numbers (5-tuple). Provides an equal-cost multi-path (ECMP) entropy benefits on the underlay (core) network by calculating the outer-source UDP The following are the main features of VxLAN GPE Tunnel:Įncapsulates layer-3 packets directly into a VxLAN tunnel without any layer-2 bridge-domain requirements or dependencies. Provide protocol typing, OAM and versioning capabilities. VxLAN GPE (Generic Protocol Extension) is intended to extend the existing VxLAN protocol to
Need not use transport layer port numbers to identify tunnel payload, rather it encourages encapsulations to use their own It provide the ability to define Operations, Administration, and Maintenance (OAM) protocols. The protocol being encapsulated and therefore is currently limited to encapsulating only Ethernet frame payload, nor does The need to provide increased visibility and diagnostic capabilities within the overlay. As data centers evolve, the need to carry other protocols encapsulated in an IP packet is required, and
Virtual eXtensible Local Area Network (VxLAN) defines an encapsulation format that encapsulates Ethernet frames in an outer
