Hello,
I have problem with selective no-translation TYPE7 LSA to TYPE5 LSA on ABR.
Scheme: https://ibb.co/mhbxwmy
R3 announce connected routes by function:
function allow_network()
prefix set localnet;
{
localnet = [ 10.0.0.0/8{16,30 ];
ospf_metric1 = 10;
if net ~ localnet then
return true;
else
return false;
}
R3 > show ospf lsadb

R1 (ABR) should translate TYPE7 do TYPE5 (GLOBAL AREA) but he does not
do it for all. For example 10.19.80 is only at LSADB AREA6 - TYPE7.
Routes for 10.19.80.0/24 looks the same as for translates for example
10.19.141.0/24

config from R1:
area 0.0.0.0 {
networks {
xx.xx.92.4/30;
xx.xx.92.8/30;
};
interface "vlan3900" {
cost 100;
type ptp;

nssa;
translator yes;
networks {
xx.xx.92.252/30;
};
interface "vlan3960" {
type ptp;
};
};
it happens on every version that I used (1.6.1, 1.6.4, 1.6.6). After
restart bird process, others prefixes are not translated. In effect R2
does not know route for not tranlsated to TYPE5 routes.
