Okay cool. What benefit does the tunnel interface give you over a virtual
link in this scenario?

Yes but also use a tunnel over a virtual-link.

So basically configure the area range command on both R5 and R1?

Thanks for taking the time to look at this.

Regards,
Greg

Greg,
This is a valid solution:

R1:
hostname Rack1R1
!
interface Loopback0
   ip address 150.1.1.1 255.255.255.0
!
interface Tunnel0
   ip address 163.1.15.1 255.255.255.0
   tunnel source Loopback0
   tunnel destination 163.1.35.5
!
router ospf 1
   area 0 range 150.1.4.0 255.255.254.0
   redistribute connected subnets route-map CONNECTED->OSPF
   network 163.1.13.1 0.0.0.0 area 1
   network 163.1.15.1 0.0.0.0 area 0
!
route-map CONNECTED->OSPF permit 10
   match interface Loopback0

R5:
hostname Rack1R5
!
interface Tunnel0
   ip address 163.1.15.5 255.255.255.0
   tunnel source Serial0/0.35
   tunnel destination 150.1.1.1
!
interface Loopback0
   ip address 150.1.5.5 255.255.255.0
!
router ospf 1
   router-id 150.1.5.5
   area 0 range 150.1.4.0 255.255.254.0
   network 150.1.5.5 0.0.0.0 area 0
   network 163.1.15.5 0.0.0.0 area 0
   network 163.1.35.5 0.0.0.0 area 1

R3:
Rack1R3#show ip route 150.1.4.0 255.255.254.0
Routing entry for 150.1.4.0/23
    Known via "ospf 1", distance 110, metric 782, type inter area
    Last update from 163.1.35.5 on Serial1/0, 00:03:54 ago
    Routing Descriptor Blocks:
    * 163.1.35.5, from 150.1.5.5, 00:03:54 ago, via Serial1/0
        Route metric is 782, traffic share count is 1

Greg,
I'll lab this up tonight and take a look at the issue. There
should be a very easy solution that I'm going to test out.

Sorry Brian I already wiped the config and moved on to the next lab.
Actually Ali Hasan posted the same question on the IE forum but got no
replies.

Can you send the output of the "show ip route 150.1.0.0 255.255.0.0
longer-prefixes" from R3?

Thanks!

Hello Brians,

Task 4.6 of Volume 1, Lab 7 requires you to use the area range command
to
summarize the 150.1.4.0 routes but later in the excercise you then show
a
virtual link being established to R1 causing it to receive the /32
subnets
from Area0 and forward them R3.

I was just wondering how that would be addressed? I used a distribute
list
on R3 but I was wondering why this wasn't addressed in the solution
guide?
If its just an oversight thats cool but it had me scratching my head for

some time.

I guess a related question would be can you filter intra-area routes
between
routers in the same area?

Thanks,
Greg
