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...
