 |
|
I migrate to Gentoo from another distrib and try to configure static network with one bridge on one port.
My /etc/conf.d/net is:
| Code: | config_eth0="null"
bridge_forward_delay_br0=0
bridge_hello_time_br0=1000
bridge_stp_state_br0=1
bridge_br0="eth0"
config_br0="192.168.x.16/24 2a03:x::16/64"
routes_br0="default via 192.168.x.1
default via 2a03:x::1"
dns_servers_br0="192.168.x.7 192.168.x.1 2a03:x::7 2a03:x::1"
dns_search_br0="my.search.domain"
rc_net_br0_need="net.eth0" |
The network is work without any visible issues but the syslog sometimes starting to fill up with "errors":
| Code: | Aug 03 14:35:26 [kernel] [272986.554275] br0: port 1(eth0) received tcn bpdu
Aug 03 14:35:26 [kernel] [272986.554296] br0: topology change detected, propagating |
The messages appear every 10 seccond and not disapper on reboot.
I do not find any issues with cable (router not detect any disconnects). I do not find any issues with ip4 or ip6 addres duplications.
On my previous distrib I have basicly the same config and have no issues.
How can I fix this? |

Thank you. I already found this solution but it didn't help. I already change the cable and my connection is stable.
Is any tools or configs can help me found the source of this filling log messages? |

You could use wireshark and check from which network device you receive these tcn bpdu ... maybe you have more than one bridge in your network ... you know the loop problem ?

I don't know anything about "loop problem" can you give me a link?
My network is very simple:
-A gentoo pc with one port and one bridge. A pair of lxd containers connected to the bridge. All of them have static addresses.
-A router with dhcp.
-Some ethernet and wifi clients.
All of them share the same ip4/24 and ip6/64 subnet.
DHCP and Static addresses are different.
And any strange logs are only on gentoo pc  |
