Getting started with OSPFv3

11 Jul 2014

      I'm trying to get an IPv6 adjacency up and running and I'm having
issues.  I'm hoping someone can point me in the right direction here.
When I bring up bird6 I get this:

Jul 11 18:08:38 router-priamry bird6: main: Cannot find forwarding address for NSSA-LSA ::/96
Jul 11 18:08:38 router-priamry bird6: main: Cannot find forwarding address for NSSA-LSA ::/0
Jul 11 18:08:38 router-priamry bird6: main: Cannot find forwarding address for NSSA-LSA ::ffff:0.0.0.0/96

Followed by this, repeatedly, forever:

Jul 11 18:21:15 router-priamry bird6: OSPF: Received non-hello packet from unknown neighbor (src fe80::c67d:4fff:fe9f:945, iface em0)

The relevant interface config:

em0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0 mtu 1500
        options=9b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM>

        inet 70.32.199.65 netmask 0xffffffff broadcast 70.32.199.65 vhid 1
        nd6 options=23<PERFORMNUD,ACCEPT_RTADV,AUTO_LINKLOCAL>
        media: Ethernet autoselect (1000baseT <full-duplex>)
        status: active
        carp: MASTER vhid 1 advbase 1 advskew 0

The bird config:

log syslog all;
debug protocols all;
router id 70.32.199.66;

protocol kernel {
        learn;                  # Learn all alien routes from the kernel
#       persist;                # Don't remove routes on bird shutdown
        scan time 20;           # Scan kernel routing table every 20 seconds
        import all;             # Default is import all
        export all;             # Default is export none
#       kernel table 5;         # Kernel table to synchronize with (default: main)
}

# This pseudo-protocol watches all interface up/down events.
protocol device {
        scan time 10;           # Scan interfaces every 10 seconds
}

protocol ospf main {
#       tick 2;
#       rfc1583compat yes;
        import all;
        export all;
        area 900 {
                stub;
                nssa;
                interface "em0" {
                        hello 1;
                        dead 4;
                        type broadcast;
                };
        };
}

And the config from the Cisco side:

interface Vlan881
 ip address 70.32.199.94 255.255.255.224
 ip policy route-map LAB
 ipv6 enable
 ipv6 ospf hello-interval 1
 ipv6 ospf 100 area 900
end
!
route-map LAB permit 5
 match ip address LAB
 set ip next-hop 10.120.0.93
!
ip access-list extended LAB
 permit ip 70.32.199.64 0.0.0.31 any
!
ipv6 router ospf 100
 router-id 10.120.9.1
 area 900 nssa
 passive-interface default
 no passive-interface Vlan881
 ...
 redistribute connected
