Roger,
You must change the OSPF Cost to be lower on the Ethernet interface on
R3. R5 will then prefer the routes from R3.
R1:
interface Ethernet0
ip address 150.10.20.1 255.255.255.128
ip ospf cost 150
----
R3:
interface Ethernet0
ip address 150.10.20.3 255.255.255.128
ip ospf cost 100
----
r5#sh ip route
Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP
i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, * - candidate
default
U - per-user static route, o - ODR
Gateway of last resort is not set
O E1 200.100.100.0/24 [110/129] via 150.10.60.6, 00:02:54, Serial1.1
B 198.5.51.0/24 [200/0] via 150.10.6.6, 00:02:25
C 200.150.150.0/24 is directly connected, Loopback1
B 198.5.53.0/24 [200/0] via 150.10.6.6, 00:02:25

B 198.5.54.0/24 [200/0] via 150.10.6.6, 00:02:25
150.10.0.0/16 is variably subnetted, 17 subnets, 3 masks
O E2 150.10.30.0/24 [110/65] via 150.10.10.3, 00:02:55, Serial1.2

Hi ,
I have a question regarding CCBootcamp Lab 20.
In Task Three - OSPF configuration ,
No. 5 . It says that R5 should prefer to learn about networks configure
on
Ethernet Segments of R3 and R1 via R3 only.
How is this accomplished ?
I look through the config but found no clue to this ?
Any body helps ?
Regards
roger
