From d871fe9c4c65de87232802ed54b263c9b2824391 Mon Sep 17 00:00:00 2001 From: Christian Breunig Date: Thu, 28 Aug 2025 14:46:48 +0200 Subject: bgp: T7760: deprecate per bgp vrf instance system-as node Originating from the bug in T7665. To avoid potential issues down the line - and given that there's no compelling technical reason to retain the system-as CLI node under per-VRF BGP configuration, which cannot be achieved through alternative means - the maintainers have collectively decided to deprecate the following command: set vrf name protocols bgp system-as Starting with VyOS 1.4.4, this CLI command will be considered deprecated. While it will still be accepted, it will no longer have any operational effect. A deprecation warning will be displayed at commit time, indicating that the BGP ASN from the global BGP configuration is now used instead. A migration script will handle the transition and perform the following actions: * Ensure a global BGP configuration exists; if not, initialize one. * Iterate over all configured VRFs to determine whether a BGP instance exists * For any insance, update the configuration to use the global system-as and apply the local-as ASN no-prepend replace-as option on all affected neighbors to preserve existing behavior. * If a neighbor is already configured with a local-as directive, that neighbor will be excluded from the migration process, as it already follows a custom configuration. * Add allowas-in per neighbor option. Required to not deny prefix received updates due to as-path contains our own global ASN. --- interface-definitions/include/version/bgp-version.xml.i | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'interface-definitions/include/version') diff --git a/interface-definitions/include/version/bgp-version.xml.i b/interface-definitions/include/version/bgp-version.xml.i index c90276151..21fddf9ae 100644 --- a/interface-definitions/include/version/bgp-version.xml.i +++ b/interface-definitions/include/version/bgp-version.xml.i @@ -1,3 +1,3 @@ - + -- cgit v1.2.3
