From 73557d68b1cb54714fc0c3652a9ab29559da00ee Mon Sep 17 00:00:00 2001 From: Christian Poessinger Date: Mon, 29 Mar 2021 18:30:28 +0200 Subject: bgp: T1711: remove ASN tagNode and move to "local-as" Every time when set configuration bgp, you need set AS number. There is very less benefit in this system so the AS number is moved from a tagNode level down to a leafNode with the name "local-as", same as on the neighbor or peer-group level. This changes the CLI configuration from: set protocols bgp 100 neighbor 10.10.1.2 remote-as 200 to set protocols bgp local-as 100 set protocols bgp neighbor 10.10.1.2 remote-as 200 --- src/migration-scripts/bgp/0-to-1 | 61 ++++++++++++++++++++++++++++++++++++++++ 1 file changed, 61 insertions(+) create mode 100755 src/migration-scripts/bgp/0-to-1 (limited to 'src/migration-scripts') diff --git a/src/migration-scripts/bgp/0-to-1 b/src/migration-scripts/bgp/0-to-1 new file mode 100755 index 000000000..a70b52909 --- /dev/null +++ b/src/migration-scripts/bgp/0-to-1 @@ -0,0 +1,61 @@ +#!/usr/bin/env python3 +# +# Copyright (C) 2021 VyOS maintainers and contributors +# +# This program is free software; you can redistribute it and/or modify +# it under the terms of the GNU General Public License version 2 or later as +# published by the Free Software Foundation. +# +# This program is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
