Hi,

I got completely stuck on this question I hoped someone maybe able to help me
out. The topology is as follows

AREA 0=Router4====area 47=====Switch1=area0

The question was (word for word):-

Configure OSPF area 47 on the Ethernet segment between R4 and SW1
Devices in OSPF area 47 should only receive LSA of type 1, 2 and a default of
type 3.

To me that says configure Router 4 with "area 47 stub no-summary"
The problem then is that I cant configure a virtual-link to SW1s area0.
Is the answer on router4:-
configure area47 as normal area
configure "default-information orginate always" on router4
configure "area 47 filter-list prefix prefix-list"
ip prefix-list prefix-list permit 0.0.0.0/0 le 32

Can anybody suggest for sure?

Many thanks

Alex
