Hi, Good news: cannot reproduce the problem: booted new ubuntu vm, installed frr from source, was able to run topotests without problem. I do not know what was the underlying cause of my yesterday's problem. Thanks for your help, Aleksey On Mon, Dec 2, 2019 at 10:35 PM Aleksey Romanov <aleksey@voltanet.io> wrote:
Hi Donald,
Mark helped me using our local slack.
I could not be 100% sure yet until I repeat all the steps but here is the problem as I understand it today.
I built and installed frr for ubuntu 18.04 according to http://docs.frrouting.org/projects/dev-guide/en/latest/building-frr-for-ubun..., in this case shared libraries are placed in /usr/lib/frr. It creates some subtle problem with vtysh when running topotests (and topotest only). It was resolved by adding file with /usr/lib/frr path to /etc/ld.so.conf.d and running ldconfig.
The topotest instructions http://docs.frrouting.org/projects/dev-guide/en/latest/topotests.html suggest slightly different set of configure options and I guess they do not hit this problem because of different shared libs placement - but as I said I did not try it yet.
Thanks,
Aleksey

Aleksey -
Debugging topotests over email might end up being quite fun. I would suggest logging into the FRRouting slack and opening a discussion there and we can start talking through what is going wrong. I am suggesting this because when something goes wrong I end up having to look in a bunch of different places to understand the test and to fix it.

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
http://docs.frrouting.org/projects/dev-guide/en/latest/topotests.html
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.
