Hi,
This is pretty basic but I think my mind has drawn a blank. I am struggling to make my 3 routers communicate with my ISP routers. Its simple, I need to add the route within OSPF of the other routers. I cant seem to get it right and can only ping from router one.
My assignment is due monday so any fast help is great. My lecturer mentioned he wanted a loopback on the ISP but im not sure what this means either. I think the stress has got to me now :)
I uploaded my packet tracer file. Any username and passwords are cisco.
Any help would be appreciated.

@Georg Pauwen fixed it
I had to add
network 145.45.5.0 0.0.0.255 area 0
to the warmingham router :)
Then the default route worked.

Hello,
it looks like your ISP router needs a default route:
ip route 0.0.0.0 0.0.0.0 Serial0/1/0

Hello,
the static default route will make the ISP router reachable from everywhere. What exactly is the assignment, does the ISP router have to be part of OSPF ?

Hello,
either that, or add the static default route on the Warmingham-Router as indicated in my last post.

Hello,
add:
ip route 0.0.0.0 0.0.0.0 Serial0/1/1
to the Warmingham-Router...

my guess ISP does not have routes to you.
if u add ip route 0.0.0.0 0.0.0.0 145.45.5.100 on Wahsington router,
also, add routes back to you on ISP. ISP should have static routes back to you,
Ping is 2 -way process. you need route to me, then I need route back to you.
it is not likely that ISP will have a default route to you or me; ISP runs static or BGP .
it works now

Hello
Remove the no passive-interface serial 0/1/1 from Warmingham HQ and enable ospf between that rtr and ISP then you establish connectivity you desire.
Warmingham
router ospf 1
no passive-interface serial 0/1/1
network 145.45.5.1 0.0.0.0.0 area 0
ISP
router ospf 1
network 145.45.5.100 0.0.0.0.0 area 0
