From ce361fe12c430c792361479e5b5b3228141fd36f Mon Sep 17 00:00:00 2001 From: Christian Poessinger Date: Wed, 7 Apr 2021 14:53:49 +0200 Subject: vrf: T3344: re-add virtual network identifier Commit 548d9057e3e (vrf: T3344: move dynamic routing protocols under "vrf name protocols") temporary removed the possibility to specify the VNI for a given VRF to to changing of the CLI configuration nodes. As VNI is set inside zebra, we can re-use the now widely deployed frr python library to configure and change the configuration without any interference to other FRR daemons. --- src/conf_mode/vrf.py | 21 +++++++++++++++++++++ 1 file changed, 21 insertions(+) (limited to 'src/conf_mode') diff --git a/src/conf_mode/vrf.py b/src/conf_mode/vrf.py index 414e514c5..a39da8991 100755 --- a/src/conf_mode/vrf.py +++ b/src/conf_mode/vrf.py @@ -23,14 +23,18 @@ from vyos.config import Config from vyos.configdict import node_changed from vyos.ifconfig import Interface from vyos.template import render +from vyos.template import render_to_string from vyos.util import call from vyos.util import cmd from vyos.util import dict_search from vyos.util import get_interface_config from vyos import ConfigError +from vyos import frr from vyos import airbag airbag.enable() +frr_daemon = 'zebra' + config_file = r'/etc/iproute2/rt_tables.d/vyos-vrf.conf' def list_rules(): @@ -123,6 +127,7 @@ def verify(vrf): def generate(vrf): render(config_file, 'vrf/vrf.conf.tmpl', vrf) + vrf['new_frr_config'] = render_to_string('frr/vrf.frr.tmpl', vrf) return None def apply(vrf): @@ -210,6 +215,22 @@ def apply(vrf): if 1000 in [r.get('priority') for r in list_rules() if r.get('priority') == 1000]: call(f'ip {af} rule del pref 1000') + # add configuration to FRR + frr_cfg = frr.FRRConfig() + frr_cfg.load_configuration(frr_daemon) + frr_cfg.modify_section(f'^vrf [a-zA-Z-]*$', '') + frr_cfg.add_before(r'(interface .*|line vty)', vrf['new_frr_config']) + frr_cfg.commit_configuration(frr_daemon) + + # If FRR config is blank, rerun the blank commit x times due to frr-reload + # behavior/bug not properly clearing out on one commit. + if vrf['new_frr_config'] == '': + for a in range(5): + frr_cfg.commit_configuration(frr_daemon) + + # Save configuration to /run/frr/config/frr.conf + frr.save_configuration() + return None if __name__ == '__main__': -- cgit v1.2.3
