Hi Pragya Nand,
The reachability from 1.1.1.1 to 2.2.2.3 on the host is failing as ARP
request 1.1.1.1 -> 2.2.2.3 gets dropped in VPP. Normally both target and
source IPs for ARP are expected to be in the same subnet of the Rx
interface. You can try enabling proxy ARP on the Rx interface for the d
HI Sastry,
For VPN v4 session, labelled IPvx route(for ingressing) and mpls route(for
egressing) need to be set up. Can you check if they are getting
programmed correctly into VPP. The Labeled route seems to be OK from the
o/p you have pasted.
Thanks,

Hi Sastry,
The loop issue with BFD in our case we resolved by installing mpls php
route with eos. Earlier we had installed the mpls php route without eos.
Our case was mpls php with IPv4 forward. However from the config you shared
your case seems to be with MPLS ingress??

We are observing a random crash in code that we have added in VPP. The

We have been rebasing our downstream vpp version to the upstream version

Hi Ben,
The problem seems to be due to external libraries that we have linked with
VPP. These external libraries have not been compiled with ASAN.
I could see that when those external libraries were suppressed through the
MyASAN.supp file, VPP started running with ASAN enabled.

I am not able to run VPP with ASAN. Though we have been using VPP for

Hello All,
In *19.08** VPP version* we are seeing a crash while accessing the

As such the FIB programming is happening in the main thread and in one of

Another solution is to redirect the traffic from punt node to your feature
