[vpp-dev] EVPN mac/IP routes are advertised when tunnel in created on kernal but not working when vxlan tunnel is on VPP #vpp-dev

When I create vxlan tunnel in VPP, loop1 and add them to bridge-domain,  I dont't see mac/ip routes adv to the remote VTEP. But If I do same steps in linux kernal that seems to work fine and mac/ip routes are adv to remote VTEP as expected.  Can you please let me know why VPP is not working int

Pim, Thanks for the reply. I pulled in https://gerrit.fd.io/r/c/vpp/+/31122. Set the default netns in startup.conf. Now it works. tap3 doesn

[vpp-dev] VRRP master gratuitous ARP request with physical MAC address

Hi all, We have another problem/question related to VRRP. When the router connect to the setup has disabled MAC learning, the ARP table on the router doesn't have the virtual MAC for the VIP but the physical MAC of the interface on the VRRP master. Tracing showed that GARP is sent from VIP wit

Hi Sudhir, I am working on a few bugfixes for ASan. Right now, I'd recommend to use ASan in debug builds only, there are several issues that need to be fixed in release mode. Best ben > -Original Message- > From: vpp-dev@lists.fd.io On Behalf Of Sudhir CR via > lists.fd.io > Sent: jeud

[vpp-dev] VPP 2110 with AddressSanitizer enabled

Hi Team, We compiled vpp code with AddressSanitizer enabled. We used the below command to compile code. *sudo make rebuild-release VPP_EXTRA_CMAKE_ARGS=-DVPP_ENABLE_SANITIZE_ADDR=ON* we are starting vpp with below command *sudo ./vpp -c /etc/vpp/startup.conf* But vpp startup is failed with be

Re: [vpp-dev] Tx packet drops (dpdk tx failure) Error seen and no packet flow possible after this

Tx drops usually mean the interface does not keep up with the packet rate and VPP/DPDK has to drop the packets because the tx queue is full. If it is caused by short bursts of traffic, you can try to increase the tx queue size to better absorb those bursts. If the interface is just too slow, you'

Re: [vpp-dev] Tx packet drops (dpdk tx failure) Error seen and no packet flow possible after this

Hi Girish, One suggestion is that try to update VPP to the latest stable version ,as your VPP version looks very old. Secondly ,please attach what kind of configuration you have done on VPP before firing traffic so that ppl could analyse. Thanks, Akash On Thu, Feb 24, 2022, 17:28 Girish NL wro

Re: [vpp-dev] Tx packet drops (dpdk tx failure) Error seen and no packet flow possible after this

Hello All, Could somebody kindly point out what can cause "Tx packet drops (dpdk tx failure)" errors and packet drops? Was this observed by anybody and any solution was adopted in the latest VPP versions? Kindly help as we are unable to figure out the reason for such drops. Thanks in advance. Re

Re: [vpp-dev] linux-cp created tap interface send out packets issue

Wei, I think Linux CP starts a netlink listener in what is configured as the default netns (in your case, implies this is the default namespace). This means any 'ip' command you issue from Linux side won't be seen by VPP. A few comments: - You are running 21.06 which is not complete. Please buil
