routing ospf between two area (backbone & nssa)

Hi every one,

I have an issue with routing on VS (maestro) witch is routing between two area (an abr role) :

- area 0.0.0.1 is an nssa with no summary (totally stubbed no so stubby area)

- area backbone

Both are running with the same instance (default) but i never receive default route advertisement on routers inside area 0.0.0.1. However, network from area 0.0.0.1 are well known outside. This setup work fine with a "classic" router (but i lose many filtering capabilties).

See below an extract from ospf VS and a router inside my area

on VS

set ospf instance default graceful-restart-helper on

set ospf instance default area backbone on

set ospf instance default interface wrp320 area backbone on

set ospf instance default area 0.0.0.1 on

set ospf instance default interface bond10.2517 area 0.0.0.1 on

set ospf instance default area 0.0.0.1 nssa on

set ospf instance default area 0.0.0.1 nssa default-metric-type 1

set ospf instance default area 0.0.0.1 nssa import-summary-routes off

set ospf instance default area 0.0.0.1 nssa translator-role candidate

on router inside 0.0.0.1 (an asbr)

ospf 2517 router-id 172.17.0.2 vpn-instance TEST

asbr-summary 172.16.0.0 255.240.0.0 cost 5000

import-route direct

area 0.0.0.1

network 172.17.0.0 0.0.0.7

nssa

it's work if i replace my VS with a "classic router" with this kind of setup

router ospf 1000
log-adjacency-changes
area 0.0.0.1 nssa no-summary
network 172.17.0.0 0.0.0.7 area 0.0.0.1
network 192.168.0.0 0.0.0.255 area 0.0.0.0

Thx for any helpfull,

Regards,
