Re:[nvo3] BFD over VXLAN: Trapping BFD Control packet at VTEP

Hi Anoop, Due to the fact that a variety of Tunnels could be used under the NVO3 architecture, as an example, below figure illustrates the format of MPLS packet over Geneve Tunnel. 0 1 2 3 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1

Hi Xiao Min, I think we would need more detail around the use case below. What does the MPLS packet over Tunnel look like? Thanks, Anoop On Wed, Sep 25, 2019 at 11:37 PM wrote: > Hi Anoop, > > > Thanks for your comments. > > Considering a scenario where TS1 has an MPLS access (i.e.

Hi Anoop, Thanks for your comments. Considering a scenario where TS1 has an MPLS access (i.e. MPLS-Packet over Tunnel between NVEs) to VNI1, TS3 has an Ethernet access (i.e. MAC-Frame over Tunnel between NVEs) to VNI1, then how can TS1 and TS3 share one VAP? Best Regards, Xiao

Hi Joel, Thanks for your comments. I don't think the VNI could own IP address and MAC address, if the BFD messages are originated and terminated at the VNI, then what addresses would be used by the BFD messages? As to the VAP, RFC8014 defines it as below: "On the NVE side, a VAP is a

>>> Some people may argue that all Tenant Systems connecting to the same Virtual Network MUST share one VAP, if that's true, then VAP1 and VAP3 should merge into one VAP and my explanation doesn't work. Copying to NVO3 WG to involve more experts, hope for your clarifications and comments. >>> I
