GitHub user miloserdoff closed a discussion: VM does not see virtual router 
after migration to another host

Good day. I have 2 hosts, a virtual router and a VM.

The virtual router and VM are on host1

When the virtual machine and the virtual router are on the same host host1, I 
can send ping 10.1.1.1 (the IP address of the virtual router) and I will 
receive a response.

But when I migrate the virtual machine to another host host2, and the virtual 
router remains on host host1, I cannot send ping 10.1.1.1

What could be the problem?
