[quagga-dev 16742] Problem in route map operation - Important! - UPDATE

[Marcin Kabiesz]

Hello,
in all versions released after version 0.99.24.1, ie from 1.x to
current 1.2.4, there is a problem with route map initiation. This is
manifested in the fact that when the session and / or service, e.g.
bgpd, is restarted, the network addressed to the route-map is not
processed. Only after compiling the session and adding this network to
use the route map can you see it in advertised-routes. Below I am
sending the configuration of the client session on the side of the
service bgpd so that you can test it and possibly write / release the
appropriate patch.
0.99.24.1 -> stable and working
1.x to 1.2.4 (current) -> not working
This is an example of a configuration that should simulate the error
by switching between stable version 0.99.24.1 on which it works and
some newer version from version 1.x.

Please, do not ignore the problem. If the message has reached the
wrong place, please give it to the appropriate person responsible for
the Quagga package and its source code.

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
