Thanks for help!
I tested both ways: stub and nssa. In stub i can't generate 0/0 prefiks, in nssa area it works. I have question about neighbor session between routers. It is necessary or not recommended ? When i added neighbor statement between routers i noticed unstable behavior.
Below my config, on both routers are the same
export ospf-global-export;
import ospf-global-import;
area 0.0.0.100 {
nssa {
default-lsa {
default-metric 10;
metric-type 1;
type-7;
}
no-summaries;
}
interface ae2.100 {
interface-type nbma;
priority 200;
hello-interval 10;
inactive: neighbor 1.1.1.14 eligible;
neighbor 1.1.1.5;
neighbor 1.1.1.6;
inactive: poll-interval 30;
}
}
show policy-options policy-statement ospf-global-export
term 1 {
from {
route-filter 0.0.0.0/0 exact;
}
then {
metric 55;
accept;
}
}
term default {
then reject;
}
show policy-options policy-statement ospf-global-import
term 1 {
from {
route-filter 0.0.0.0/0 exact;
}
then reject;
}
term default {
then accept;
}
my bird.cfg on servers
protocol ospf MyOSPF {
tick 2;
import all;
export all;
rfc1583compat yes;
area 100 {
nssa;
interface "bond0" {
hello 10;
type nbma;
neighbors { 1.1.1.9 eligible;
1.1.1.14 eligible;
and my scenario:
