Hey fellows,

Do not forget to set MTU 1492 inside Dialer interface for OSPF going up.

!
interface Dialer 1
 mtu 1492
!

Try this, before any other changes.

Alexandre.

What you need to do on R3 is add an IP address to any of the interfaces as
far as I am aware.

There are no IP's at the moment so OSPF cant "run" on any of the interfaces

Try setting up a loopback with an IP address on it and see if it works

Hello Experts,

I am facing some issues in forming the OSPF neighborship with the following
setup and the configurations .

R3 (e0/0) -------- (f0/3 )SW1(f0/4)--------- (e0/0) R4

*R3*

interface Ethernet0/0
 no ip address
 full-duplex
 pppoe enable group CISCO
 pppoe-client dial-pool-number 1
end
!

 ip address dhcp
 encapsulation ppp
 dialer pool 1
end
!
router ospf 1
 log-adjacency-changes
 network 0.0.0.0 255.255.255.255 area 0
