Hi there,
I'm not sure if anyone else has seen this issue but I have been getting
this issue repeatably today, where OSPFv3 just stops working due to "bad
DBDES packet from nbr", I haven't changed anything and it has been
working fine for months.
What's the best way to troubleshoot this?
The neighbor starting with 193. is a Debian 10 machine, 185 and
192.168.2.1 are EdgeOS running Bird 2.0.8.
2021-08-31 17:23:53 <RMT> ospfv3_v4: Bad DBDES packet from nbr
192.168.2.1 on wg0 - I-bit mismatch (7)
2021-08-31 17:23:53 <RMT> ospfv3_v6: Bad DBDES packet from nbr

OSPF3 configuration:
-------------------------------------------------------------------------------------------------
protocol ospf v3 ospfv3_v4 {

import filter internel_prefixes;
export filter internel_prefixes;
#export where (source = RTS_STATIC) || (source = RTS_DEVICE);

interface "lo*" { stub; };
interface "tun0" { type ptp; cost 10; stub no; };
interface "wg0" { type ptp; cost 20; stub no; };
interface "wg1" { type ptp; cost 30; stub no; };
};
}
protocol ospf v3 ospfv3_v6 {
ipv6 {
import filter internel_prefixes;
export filter internel_prefixes;
#export where (source = RTS_STATIC) || (source = RTS_DEVICE);
};
