Re: [vpp-dev] TCP connection using VPP

Hi Chetan, Interesting. As far as I know, there haven’t been any new updates in that area. It would be great if somebody ported the code to use vcl as opposed to the session layer directly. That would ensure compatibility going forward … Regards, Florin > On Mar 2, 2021, at 12:18 PM,

Re: [vpp-dev] TCP connection using VPP

Thanks Florin. I was able to figure out using the vcl.conf.  I am using that version because that seems like the last version compatible with SPDK. Is there a later version of it that can still work with SPDK?  Thanks,Chethan On Tuesday, March 2, 2021, 09:38:34 PM GMT+5:30, Florin Coras

Re: [vpp-dev] TCP connection using VPP

Hi Chetan, That is a pretty old version of vpp, so I would first recommend updating to something newer. Regarding the specific issue you are hitting, it’s hard to tell what’s causing it from your description. Maybe also try iperf3 like here [1] and see if that works. If that’s still not

[vpp-dev] TCP connection using VPP

Hi, I am using VPP 19.04.2. I was able to establish "ping" connectivity between 2 VPP instances running on 2 VMs. I am not able to establish TCP socket level connectivity. When I use sock_test_(server|client), the server just sits there waiting for the client and the client hangs as well.

Re: [vpp-dev] tcp connection

I found the problem. I was using the loopback interface of linux as loopback of VPP which is not correct, since it is not recognized in VPP. So packet are dropped in ip4-lookup node. I thought that it is the problem in tcp because I was sending tcp SYN without VPP's awareness of this sending. But

Re: [vpp-dev] tcp connection

are you aware that vpp doesn’t do LDP? VPP is dataplame, and expect that external control plane is present and takes care for programming mpls fib. — Damjan > On 17 Jun 2018, at 15:11, Gulakh wrote: > > Hi, > I am having a problem when LDP attempts to setup a session. > According to

[vpp-dev] tcp connection

Hi, I am having a problem when LDP attempts to setup a session. According to Wikipedia's LDP page , LDP first exchanges packets on UDP and then start a session by setting up TCP connection. UDP packets from control plane to data plane are

Hi Hang, A common problem when working with tcp/udp in these sort of setups is offloading. Have you tried doing something like: ethtool --offload vpp0 rx off tx off ip netns exec ns0 ethtool --offload vethns0 rx off tx off HTH, Florin > On Feb 21, 2017, at 10:19 PM, Hang Shi
