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

 network 1.1.1.1 0.0.0.0 area 10
 network 172.16.1.5 0.0.0.0 area 10

R5#sh ip os nei
