### End-host configuration files
It's not entirely normal to run FRR daemons on end-hosts. However, they still
need their IP address and default route configured and the options are to do it
either from a Python script or use FRR daemons. Using the FRR `zebra` and
`staticd` daemons makes it easier to configure the end-hosts together with the
actual routers. However, they should not be running any daemon other than
`zebra` and `staticd`.
### A note on VTY shell
The recommended way of connecting to daemons by FRR is to use the [VTY
shell](http://docs.frrouting.org/en/latest/vtysh.html) which can connect to all
the daemons simultaneously. Unfortunately, in our configuration where multiple
instances of the same daemon run on the same machine in Mininet, it gets
confused and it doesn't connect as expected. Therefore, you can't use the VTY
shell with Route 0.
