Comment 9 for bug 1883845

Ok, thanks for the info. I have some more clarity now.

The two VMs (VM1 and VM2) are in different tenant networks and hence they wont be able to ping each other on the fly. You need to add a route for that to happen. Could you please try the following commands in VPP:

vpp# ip route 200.200.200.0/24 table 1 via 200.200.200.1 next-hop-table 2
vpp# ip route 100.100.100.0/24 table 2 via 100.100.100.1 next-hop-table 1
