Hi Leigh,
R3 would get this summary and the /24 as it is part of area 0. The injected
network and the summary would go into area 0 as all lsa's do. Another area
would receive only the summary.
For example your topology
R1 -- area 1 -- R2 -- area 0 -- R3 -- area 4 -- R4
Router 3 will see both routes but R4 will only see the summary.
Regards
Lee.

Subject: OSPF area range
Anyone,
I've put in a area range on a router.
It sends it out to the correct boxes attached to it, BUT!! It also send
out the routes that I'm trying to summerise !!!
I can't seem to see why. Any thoughts ?
R1 -- area 1 -- R2 -- area 0 -- R3
R1 has the addresses 12.12.8.0 - 9.0 - 10.0 - 11.0
On R2 I put the command:-
area 1 range 12.12.8.0 255.255.252.0
In the routing table of R3 I get:-
O IA 12.12.8.0/24 [110/139] via 12.12.23.3, 00:34:18, Serial0
O IA 12.12.8.0/22 [110/65] via 12.12.23.3, 00:34:23, Serial0
O IA 12.12.9.0/24 [110/87] via 12.12.23.3, 00:34:23, Serial0
O IA 12.12.10.0/24 [110/85] via 12.12.23.3, 00:34:23, Serial0
O IA 12.12.11.0/24 [110/86] via 12.12.23.3, 00:34:23, Serial0
O IA 12.12.13.0/24 [110/129] via 12.12.23.3, 00:36:30, Serial0
It sends out the summary, as per, but also sends out the routes too.
I wanted to cut down the table, not add to it !!!!
Time for a cup of tea methinks....
