Hi all,

I am member of ligato  vpp-agent testing team,

and in our test cases I have observed vpp crash for this testing scenario:


1 . two docker containers running vpp are started,

2.  in both containers one memif  and one loopback interfaces are configured,

3.  then bridge domains containing memif and loopback is created in both vpps.

4.  The ping between both vpps works.

5.  then I try to modify loopback ip address

6. vpp on which I modified ip crashes in 5 seconds.


Important notes:

1. the vpp will not crash, if I don't ping at all before I modify loopback ip.

2. the modified loopback interface is in that container, where slave memif is 
configured

3. If  the modified loopback interface is in that container, where master memif 
is configured,

    no vpp will crash


Please find a time to looak at this issue.


Thank you
