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

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...
