OpenBGPD is a free implementation of the Border Gateway Protocol (BGP), Version 4. It allows ordinary machines to be used as routers exchanging routes with other systems speaking the BGP protocol. The portable version (e.g. for Linux) does not have the means to influence kernel routing tables. It is only suitable for route servers/collectors.
major bugfix: bgpd 8.1 and 8.2 could send a bad COMMUNITY attribute when non-transitive ext-communities are present. A workaround is to add a filter rule to clear non-transitive ext-communities: "match to ebgp set ext-community delete ovs *". Fix a possible fatal error in the RDE when "announce add-path send all" is used. The error is triggered by an ineligible path which is wrongly distributed. Fix selection of the local nexthop for the alternate address family. This is used by 'announce IPv6 unicast' over an IPv4 session or vice-versa.
