On R6 you do not have OSPF enabled on the PPPoFR connection.
router ospf 1
router-id 2.2.2.2
area 10 virtual-link 1.1.1.1
network 2.2.2.2 0.0.0.0 area 10
network 192.1.24.2 0.0.0.0 area 24
You should always check to ensure that the OSPF neighbors have formed
BEFORE configuring a virtual link.
1) Bring up the link
2) Ping across the link
3) Enable OSPF on the link
4) Verify the OSPF neighbors
5) Configure the OSPF virtual link

Hi all,
I have problem with my configuration OSPF virtual link over ppp over
frame relay..
Configuration Scenario like this :
area 0 ---R5--- FRS/area10 --- R2--- area24 ---Cat1
my case say: R2 not use subinterface..
i already configure like this :
R5:
interface Serial0/1/0
no ip address
encapsulation frame-relay
frame-relay interface-dlci 501 ppp Virtual-Template1
no frame-relay inverse-arp !
interface Virtual-Template1
ip address 172.16.1.5 255.255.255.0
router ospf 1
router-id 1.1.1.1
area 10 virtual-link 2.2.2.2

If issued show ip ospf virtual always down whereas if we issued sh ip
ospf nei the router another site appears...
Please advice me how to fix it this problem...
