I explicitly added the table name in this updated config, but it still shows '---' in the table column: # start config router id 127.0.0.1; vpn4 table vpntab4; protocol bgp peer1 { local as 65217; neighbor 100.66.8.129 as 65217; hold time 180; vpn4 mpls { table vpntab4; import all; }; } # end config My guess was that it used the default tables for ipv4 and ipv6 -- master4 and master6 -- even though it is not receiving any routes of those types. I added entries for those types as well, but it still shows '---' for the table name. # start config router id 127.0.0.1; vpn4 table vpntab4; protocol bgp peer1 { local as 65217; neighbor 100.66.8.129 as 65217; hold time 180; ipv4 { table master4; import none; export none; }; ipv6 { table master6; import none; export none; }; vpn4 mpls { table vpntab4; import all; }; } # end config Ultimately I'm trying to use the bird-lg looking glass ( https://github.com/sileht/bird-lg) with bird, and it doesn't accept '---' as a valid table. That may be an issue with bird-lg, if '---' is an expected value. But I've defined all the table names that appear when I run `birdc show route count`, but it's still showing '---'.

Hi Chris,

From your config-file, table option is not assigned for protocol bgp peer1, but system will select the first table of given nettype. ‘---’ in the table column, that mean you don’t define table name, used the default one.

table *name*

Specify a table to which the channel is connected. Default: the first table of given nettype.

Thanks

Arvin

Following the example at https://github.com/BIRD/bird/blob/v2.0.2/doc/bird.conf.example2, I set up a simple bird config (see below).

It is working, but I am not certain what the '---' in the table column of the output of `show protocols` means. I expected the column to display vpntab4.

$ sudo /usr/local/sbin/birdc show protocols

BIRD v2.0.2 ready. Name Proto Table State Since Info peer1 BGP --- up 17:14:48.474 Established

The output of `show route count` shows that there are routes in table vpntab4:

$ sudo /usr/local/sbin/birdc show route count BIRD v2.0.2 ready. 0 of 0 routes for 0 networks in table master4 0 of 0 routes for 0 networks in table master6 9581 of 9581 routes for 9581 networks in table vpntab4 Total: 9581 of 9581 routes for 9581 networks in 3 tables

The contents of my bird.conf:

log syslog { debug, trace, info, remote, warning, error, auth, fatal, bug }; log stderr all;

router id 127.0.0.1;

vpn4 table vpntab4;

protocol bgp peer1 { local as 65321; neighbor 192.168.1.1 as 65321; hold time 180; vpn4 mpls { import all; }; }

Thanks,

Thanks for the clarification! I confirmed that I see the specified protocols using `show protocol all`: With ipv4 and ipv6 tables added explicitly: ... [preceding lines] ... Local capabilities Multiprotocol AF announced: ipv4 vpn4-mpls ipv6 ... [following lines] ... With just the vpn4 mpls table: ... [preceding lines] ... Local capabilities Multiprotocol AF announced: vpn4-mpls ... [following lines] ... I'll follow up with the bird-lg contributors, it's possible that it's not ready to handle the output from BIRD 2 for multi-table protocols.

Hi

BGP in BIRD 2 is generally a multi-table protocol (although you use just one channel / one table) and because of that associated table is not shown in 'show protocol'. You will see it in 'show protocol all'.
