Would it make more sense to reverse this part of the design? I was thinking of having each chassis its own IPv4/IPv6 address used for next-hop in announcements and OF flows installed to direct BGP control packets over to the host system, in a similar way how localport is used today for

[ovs-discuss] [OVN] random BFD timeouts between chassis

2021-03-16 Thread Krzysztof Klimonda
Hi, I'm trying to track down some issue resulting in BFD session timeouts in our deployment. What I'm seeing is that (seemingly) randomly one chassis stops sending BFD packets to some of its neighbors (seemingly one at a time, and it seems one chassis is more prone to that behavior

Of course we are fully open to redesign it if there is a better approach! And that was indeed the intention when linking to the current efforts, figure out if that was a "valid" way of doing it, and how it can be improved/redesigned. The main idea behind the current design was not to need

Hi Luis, I haven't yet had time to give it a try in our lab, but from reading your blog posts I have a quick question. How does it work when either DPDK or NIC offload is used for OVN traffic? It seems you are (de-)encapsulating traffic on chassis nodes by routing them through kernel - is this
