Hello,
I carried out additional tracking in which exactly the version of Quagga
route-map in the bgp protocol with the network command stopped working.
It follows from the herring that after the quagga-1.0.20161017 version
the quagga-1.1.0 version was released and at this point the route-map
works differently than it was previously expected. I am asking you to
take this information into account in order to speed up and help fix the
problem.

from quagga-0.XX > to quagga-1.0.20161017 = working
from quagga-1.1.0 > to quagga-1.2.4 = not working


The problem concerns the following line which is not processed correctly
in new versions of Quagga, which results in the lack of appearance in
the routing table on the other side.
"network 192.168.1.0/24 route-map testing-routemap"

"network 192.168.0.0/24" = working advertised
"network 192.168.1.0/24 route-map testing-routemap" = not working advertised

Best Regards/Pozdrawiam
Marcin Kabiesz
