Вопрос по OSPF

[fet4 46]

Привет всем.

Кто-то может объяснить следующее поведение ospf

 

Есть 3 маршрутизатора с quagga на борту.

 

 

R1

interface vlan11
 ip ospf area 0
 ip ospf authentication null
 ip ospf network broadcast
!
interface ppp-archer
 ip ospf area 1
 ip ospf authentication null
 ip ospf network point-to-point
!
router ospf
 ospf router-id 172.19.1.1
 passive-interface default
 no passive-interface vlan11
 no passive-interface ppp-archer
 redistribute connected

 

R2

interface vlan11
 ip ospf area 0
 ip ospf authentication null
 ip ospf network broadcast
!
interface ppp-archer2
 ip ospf area 1
 ip ospf authentication null
 ip ospf network point-to-point
!
router ospf
 ospf router-id 172.19.1.2
 passive-interface default
 no passive-interface vlan11
 no passive-interface ppp-archer2
 redistribute connected

 

R3

interface l2tp-r1
 ip ospf area 1
 ip ospf authentication null
 ip ospf network point-to-point
!
interface l2tp-r2
 ip ospf area 1
 ip ospf authentication null
 ip ospf network point-to-point
!
route-map CONNECTED permit 10
 match interface br-lan
!
router ospf
 ospf router-id 192.168.1.1
 passive-interface default
 no passive-interface l2tp-r1
 no passive-interface l2tp-r2
 redistribute connected route-map CONNECTED

 

Не пойму почему R1 и R2 видят маршруты друг к другу через R3.

 

Например

X.X.47.216/29 via ppp-archer2

X.X.150.200/29 via ppp-archer

 

Ожидалось что через vlan11 будут видны
