Hi As configuration changes are not yet reflected in documentation, here is a summary for adventurous testers: 0) Most features are presented in doc/bird.conf.example2 : https://gitlab.labs.nic.cz/labs/bird/blob/int-new/doc/bird.conf.example2 1) There are (currently) 8 network/route classes: ipv4, ipv6 - regular IP networks/routes vpn4, vpn6 - VPN networks/routes (IP networks with additional VPN distinguisher) roa4, roa6 - RPKI ROA records flow4, flow6 - BGP Flowspec records 2) Each routing table is defined with class (above) and contains just routes of that class (instead of 'table xxx;' use e.g. 'ipv4 table xxx;'). 3) Two tables are predefined, ipv4 table 'master4' and ipv6 table 'master6'. 4) For each network class, the first defined table of that class is considered default. 5) Protocols are connected to tables using explicitly configured channels, each channel connects the protocol to one table. Like tables, channels has class. 6) Channel is specified by a keyword, which is usually (but not always) the keyword of channel class (e.g., ipv4, ipv6, ...), and block with options. These options were moved from protocol to channel: table, import, export, all limits, preference, import keep filtered. 7) Channel may be specified without options, with expected meaning: default table (by channel class), import all, export none. 8) Some protocols require one channel of fixed class (e.g. ipv6 for ripng), Some protocols required one channel of selectable class (e.g. static), Some protocols may have multiple channels (e.g. BGP). 9) BGP supports these channels (keywords) for these AFI/SAFI pairs: ipv4 - AF 1/1 ipv6 - AF 2/1 ipv4 multicast - AF 1/2 ipv6 multicast - AF 2/2 flow4 - AF 1/133 flow6 - AF 2/133 Multicast (SAFI 2) channels connects to regular ipv4/ipv6 tables. 10) BGP channels also have these options (that were moved from BGP protocol): next hop self, next hop keep, next hop address, missing lladdr, gateway, secondary, graceful restart, add paths, igp table. 11) As usual, pipe protocol is exception - the syntax is same as in the old BIRD, two channels (to 'table' and 'peer table') are defined implicitly. 12) Some protocols were splitted and use new keywords: There is rip (for RIPv2) and ripng (for RIPng), ospf2 (for OSPFv2) and ospf3 (for OSPFv3). There is no ospf. Note that automatic naming and numbering of multiple protocols is still shared between these variants. 13) Note that with ospf2, ospf3 keywords collide with automatic names for second and third OSPF protocol. Use always explicit protocol names in these case to avoid this issue.
