The developers separately remind that in addition to OpenBSD, <strong>OpenBGPD-portable<\/strong> works on <strong>FreeBSD<\/strong> and Linux distributions <strong>Alpine, Debian, Fedora, RHEL\/CentOS, and Ubuntu<\/strong>.<\/p>\n<p><strong>What's new in OpenBGPD 9.1<\/strong><\/p>\n<ul>\n<li>outbound filter processing is accelerated by storing rules in an array and deduplicating identical filters between peers;<\/li>\n<li>error logging for attribute parsing causing session resets through UPDATE ATTRLIST error notification has been improved;<\/li>\n<li>new memory metrics for show rib memory have been added, some of which are also available in show neighbor;<\/li>\n<li>a logical error in the processing of MRT dump configurations for per-peer and per-group has been fixed.<\/li>\n<\/ul>\n<p>The main focus of OpenBGPD 9.1 is not on expanding the feature set but on improving efficiency under heavy load scenarios. The  <strong>outbound filters<\/strong>: rules are now stored in an array, and identical filters between neighbors are deduplicated. According to the project's authors, these changes together with those in the filter_set can reduce the duration of initial synchronization on large route servers by more than <strong>25%<\/strong>.<\/p>\n<p>Improved processing of <strong>filter_sets<\/strong> in the process <strong>RDE<\/strong>. The project has abandoned the previous scheme in favor of a linear array of set objects to reduce the number of cache misses and thus speed up the passage of routes through the filtering policy. For network operators, this essentially means a continued course toward optimizing OpenBGPD for heavy configurations and intensive BGP scenarios, where not only correctness but also predictable behavior under load is important.<\/p>\n<p>Another notable change concerns observability. In OpenBGPD 9.1, <strong>new memory metrics<\/strong>, available via the show rib memory command; some of this data is now also tracked <strong>by neighbors<\/strong> and displayed via show neighbor. At the same time, error logging for attribute parsing that can lead to BGP session resets with notification <strong>UPDATE ATTRLIST error<\/strong>. This makes diagnosing issues with sessions and routes more transparent.<\/p>\n<p>Avots: <a \ncontent=\"nofollow\" rel=\"nofollow\"
