OSPFv3 and logging (debug)

5 Dec 2013

      Hello.

Does anyone use OSPFv3 ?
My question is about monitoring.

We use OSPFv3 over tunnels and have more than one tunnel to one endpoint
over different Inet channels (different providers):
So, as example this is config of one of the side:
protocol ospf office {
        debug { states, interfaces, events };
        tick 1;
        rfc1583compat yes;
        area 0.0.0.0 {
                stub no;
                interface "ng2" {
                        cost 5;
                        type pointopoint;
                        hello 10;
                        retransmit 3;
                        transmit delay 5;
                        dead count 3;
                        wait 40;
                };
                interface "ng0" {
                        cost 10;
                        type pointopoint;
                        hello 10;
                        retransmit 3;
                        transmit delay 5;
                        dead count 3;
                        wait 40;
                };
                interface "ng1" {
                        cost 30;
                        type pointopoint;
                        hello 10;
                        retransmit 3;
                        transmit delay 5;
                        dead count 3;
                        wait 40;
                };
        };
        import filter ospfIN;
        export filter ospfOUT;
}

Show OSPF neighbors:
# birdc6
BIRD 1.3.11 ready.
bird> show ospf neighbors
office:
Router ID       Pri          State      DTime   Interface  Router IP
1.1.1.1   1         full/ptp    00:30   ng1        fe80::224:1dff:feb3:720
1.1.1.1   1         full/ptp    00:29   ng2        fe80::224:1dff:feb3:720
1.1.1.1   1         full/ptp    00:30   ng0        fe80::224:1dff:feb3:720

When any OSPF neighbor goes down/up then in log appear:
Neighbor fe80::224:1dff:feb3:720 changes state from "    full" to "   
init".
Neighbor fe80::224:1dff:feb3:720 changes state from "    init" to "   
2way".
Neighbor fe80::224:1dff:feb3:720 changes state from "    2way" to "
exstart".
Neighbor fe80::224:1dff:feb3:720 changes state from " exstart" to
"exchange".
Neighbor fe80::224:1dff:feb3:720 changes state from "exchange" to "
loading".
Neighbor fe80::224:1dff:feb3:720 changes state from " loading" to "   
full".

But OSPFv3 use link-local address for adjacency and not global IP on the
tunnel, example:
ng0: flags=88d1<UP,POINTOPOINT,RUNNING,NOARP,SIMPLEX,MULTICAST> metric 0
mtu 1500
        inet 10.255.255.1 --> 10.255.255.2 netmask 0xffffffff
        inet6 fe80::224:1dff:feb3:720%ng0 prefixlen 64 scopeid 0x12
        inet6 2001:XXX:XXXX:XXX::1:1 --> 2001:XXX:XXXX:XXX::1:2
prefixlen 128
        nd6 options=3<PERFORMNUD,ACCEPT_RTADV>

Thus it is impossible to understand exactly what neighbor (over what
tunnel) change it`s state because there is no iface name in log.
So monitoring system can say that some neighbor down/up but can`t say
over what tunnel this neighbor was working :(

Who faced with the same task ? How to solve?
Thanks.

P.S. Sorry for my english.
