Bird2 not distributing IPv6 address on dummy to OSPF

27 Sep 2021

      Hello,

I just installed fresh Debian 11 server and I need to distribute IPv6
/128 address from dummy1 interface to OSPF. Direct protocol see that
address, but neighbour not. Am I missing something?

ip -6 route
2a02:6ca3:0:2::25 dev dummy1 proto bird metric 32 pref medium
2a02:6ca3:0:2::25 dev dummy1 proto kernel metric 256 pref medium

bird> show route table master6
Table master6:
2a02:6ca3:0:2::25/128 unicast [ospf2 00:32:34.008] I (150/0) [172.20.12.25]
dev dummy1

log syslog all;
router id 172.20.12.25;
protocol device {
}
protocol direct {
        disabled;               # Disable by default
        ipv4;                   # Connect to default IPv4 table
        ipv6;                   # ... and to default IPv6 table
}
protocol kernel {
        ipv4 {
              export all;
        };
}
protocol kernel {
        ipv6 {
               export all;
        };
}
protocol static {
        ipv4;
}
protocol static {
        ipv6;
}
protocol ospf v2 {
        ipv4 {
                import all;
        };
        area 0 {
                interface "ens192" {
                        type broadcast;
                };
                interface "dummy1" {
                        stub;
                };
        };
}
protocol ospf v3 {
        ipv6 {
                import all;
        };
        area 0 {
                interface "ens192" {
                        type broadcast;
                };
                interface "dummy1" {
                        stub;
                };
        };
}
