[vpp-dev] Regarding GTPU Tunnel packet send/recieve

[Akash S R]

Hi,
I couldn't send traffic to GTPU Tunnel with respect to the teid and tteid,
but it works when I set an IP address to the particular Tunnel. Is this
always needed or else is there any other way without setting IP for a
tunnel? Kindly let me know if possible.

Regards,
Akash

Re: [vpp-dev] FD.io CI job failures

[Damjan Marion via lists.fd.io]

In addition, looks like we have test failures caused by ipsec async patch 
merged today. I submitted revert patch….

[vpp-dev] FD.io CI job failures

[Dave Wallace]

Folks,

There have been numerous VPP CI job failures in the past day & a half 
due to two known issues.


1) Starting Wednesday there were DNS lookup failures which have since 
gone away.

   See LF-IT ticket [0] for details.

2) Yesterday & today there have been lots of 'Connection Resets".
   I opened a Vexxhost ticket [1] this morning for this issue.

To date, there has not been a direct correlation identified to the move 
on Tues/Wed of some of the CSIT and Nomad servers but investigations are 
continuing to determine the root cause.


Thank you for your patience as folks work to fix the CI.

Re: [vpp-dev] ipv6 neighbor solitication sent

[hemant via lists.fd.io]

I think VPP 18 is very old.  When you get a chance, download latest VPP (I see 
a 21.01 release) or build latest VPP from gerrit.  VPP CLI between ip4 and ip6 
are confusing.  I use “show ip neighbor” to see ip6 neighbors.  Of course, if a 
neighbor does not exist, IPv6 ND has failed.  Debug ip6 ND.  For a workaround 
to ND failure, use a static ip6 neighbor – an example is given below.

 

set ip neighbor TenGigabitEthernet3/0/0 2001:420:380:dead:beef:d06:f001:2 
00:25:90:eb:e8:ec

Hi .

I am trying to establish an ipv6 static route between 2 vpp_frr ubuntu and one 
cisco 7200 . When I run sh error in vppctl I get  neighbor solitication sent 
error  . When I run ip6 sh neighbor I see nothing . What is the problem ? 

 

I am using  VPP 18 and router plugin VPPSB  and frr 7.5.

I already run the enable ip6 interface in vppctl. but when I run the sh ip6 
interface I see nothing.

Re: [vpp-dev] vcl epoll timeout fix not working on vpp 21.01

[Florin Coras]

Hi Ashish, 

Hard to say without additional details. What is the exact behavior you’re 
seeing and are you using by chance eventds for notifications? In that case 
you’ll probably need at least [1]. 

Regards,
Florin

Hi Devs,

I have deployed vpp version 21.01 on my setup .It looks like the fix for vcl 
epoll timeout is not working, even though the code for patch 
https://gerrit.fd.io/r/c/vpp/+/28173 ( 
https://ind01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgerrit.fd.io%2Fr%2Fc%2Fvpp%2F%2B%2F28173=04%7C01%7C%7C2e299522460c4d04df6f08d8df10168e%7Ca65543b9ae9349b580f00b85821adc50%7C1%7C0%7C637504607475751711%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000=EfhQl7EBtAhBrtw%2Fv4HKMGZtdexU8sF4LEc6rZz7nQw%3D=0

is present in the vppcom.c file. Could you please let me know how can I fix 
this ? Is there any other fix that I have missed ?

Thanks and Regards,
