cannot ping between router after upgrade to 2.0.3-84

hi,

i have a weird issue.

after upgrade to 2.0.3-84, i cannot ping between directly connected routers.

what should i check ?

routers affected : all router Nokia, juniper and cisco in all existing labs doesnt work. i believe Labs area working fine prior to upgrade.

i have rebooted the machine.

if the timed out ping is captured with tcpdump, the example output is :
===
$ sudo tcpdump -i vnet...
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode

Make sure you're booted with non-generic kernel:

Code: Select all

#uname -a
Linux eve-ng 4.9.40-eve-ng-ukms-2+
