I want to use OSPF with BIRD v2.0.10 on Linux.
That works well, except that the IPv6 network of the lo interface isn't
announced on OSPFv3. The IPv6 networks of the ethernet interfaces are
announced as well as the IPv4 networks of all interfaces (ethernet and
lo). The only missing is the IPv6 network of lo.
Here the OSPF config, really basic:
protocol ospf v2 {
ipv4 {
import all;
export all;
};
area 0 {
interface "eth*" {
};
interface "lo" {
stub;
};
};
}
protocol ospf v3 {
ipv6 {
import all;
export all;
};
area 0 {
interface "eth*" {
};
interface "lo" {
stub;
};
};
}
Without any active OSPF neighbor the routes show all interface networks
except that of interface lo:
# birdc show route
BIRD 2.0.10 ready.
Table master4:
10.1.1.0/24 unicast [ospf1 17:03:20.860] * I (150/10) [3.3.3.3]
dev eth0
10.1.2.0/24 unicast [ospf1 17:03:20.860] * I (150/10) [3.3.3.3]
dev eth1
3.3.3.3/32 unicast [ospf1 17:03:20.860] * I (150/0) [3.3.3.3]
dev lo
Table master6:
2001:1::/64 unicast [ospf2 17:03:25.861] * I (150/10) [3.3.3.3]
dev eth0
2001:2::/64 unicast [ospf2 17:03:25.861] * I (150/10) [3.3.3.3]
dev eth1
Here the configuration of interface lo:
# ip addr show dev lo
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN
group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
valid_lft forever preferred_lft forever
inet 3.3.3.3/32 scope global lo:1
valid_lft forever preferred_lft forever
inet6 2001::3/128 scope global
valid_lft forever preferred_lft forever
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
What am I missing?
