Hi,

1. I had built frr from recent sources on ubuntu-18.04.

2. Made sure it starts and ospfd when configured logs events in the specified log and interacts with master agentx.

3. Reset configurations to default and stopped frr.

4. Followed instructions to run topotests

sudo py.test -s -v --tb=no > /var/tmp/topo_test_out 2>&1

It seems that every test is either failed or skipped. Among other things I noticed vtysh errors that seems quite unexpected.
