Re: bird 2 and vpn4 mpls
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'. -- Elen sila lumenn' omentielvo Ondrej 'Santiago' Zajicek (email: santi...@crfreenet.org) OpenPGP encrypted e-mails preferred (KeyID 0x11DEADC3, wwwkeys.pgp.net) "To err is human -- to blame it on a computer is even more so."
Re: bird 2 and vpn4 mpls
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 '---'.

RE: bird 2 and vpn4 mpls
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

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,
