Environment
OpenWrt 19.07.3, r11063-85e04e9f46
bird2 - 2.0.7-2
target ipq806x
model Netgear R7800
# /etc/bird.conf
log syslog all;
router id 192.168.1.1;
protocol device {

protocol bfd {

protocol direct {
interface "br-lan";
ipv4; # Connect to default IPv4 table
ipv6; # ... and to default IPv6 table
}
The Kernel protocol is not a real routing protocol. Instead of communicating
with other routers in the network, it performs synchronization of BIRD
routing tables with the OS kernel. One instance per table.
protocol kernel {
scan time 10;
merge paths;
ipv4 { # Connect protocol to IPv4 table by channel
table master4; # Default IPv4 table is master4
import all; # Import to table, default is import all
export all; # Export to protocol. default is export none
};
learn; # Learn alien routes from the kernel
kernel table 10; # Kernel table to synchronize with (default: main)
}
Another instance for IPv6, skipping default options
This issue can be reproduced with the latest OpenWrt release 19.07.3, but it has been there for a long time.
A custom build of bird2 package with OpenWRT SDK doesn't have this issue.
I am not sure this is the right place to report this issue. Could anyone help with this?
