OSPF Default Route Issue....

mtehonica

Hi everyone,

Long time lurker, first time poster. Anyways, I'm working on a little OSPF lab (practice for CCNA, passed CCENT about 3 weeks ago).

I have a setup with (3) 3550's running ip routing. I'm configuring OSPF but I can't ping the internet from router/switch except the router with the actual uplink to the internet. Here is my setup...

Internet --> SW1 (fa0/47)
SW1 (fa0/4 --> SW2 (fa0/47)
SW1 (fa0/46) --> SW3 (fa0/47)

Here is my 'sh ip route' from each switch...

SW1#sh ip route
Gateway of last resort is 192.168.1.1 to network 0.0.0.0


O 192.168.30.0/24 [110/2] via 10.10.10.6, 01:28:43, FastEthernet0/46
10.0.0.0/30 is subnetted, 2 subnets
C 10.10.10.0 is directly connected, FastEthernet0/48
C 10.10.10.4 is directly connected, FastEthernet0/46
C 192.168.1.0/24 is directly connected, FastEthernet0/47
S* 0.0.0.0/0 [1/0] via 192.168.1.1

SW2#sh ip route
Gateway of last resort is 10.10.10.1 to network 0.0.0.0


O 192.168.30.0/24 [110/3] via 10.10.10.1, 01:29:09, FastEthernet0/47
10.0.0.0/30 is subnetted, 2 subnets
C 10.10.10.0 is directly connected, FastEthernet0/47
O 10.10.10.4 [110/2] via 10.10.10.1, 01:29:09, FastEthernet0/47
O*E2 0.0.0.0/0 [110/1] via 10.10.10.1, 01:29:09, FastEthernet0/47

SW3#sh ip route
Gateway of last resort is 10.10.10.5 to network 0.0.0.0


C 192.168.30.0/24 is directly connected, FastEthernet0/1
10.0.0.0/30 is subnetted, 2 subnets
O 10.10.10.0 [110/2] via 10.10.10.5, 01:29:33, FastEthernet0/47
C 10.10.10.4 is directly connected, FastEthernet0/47
O*E2 0.0.0.0/0 [110/1] via 10.10.10.5, 01:29:33, FastEthernet0/47






Here is some more information from all the switches...

(SW1)
interface FastEthernet0/46
no switchport
ip address 10.10.10.5 255.255.255.252
!
interface FastEthernet0/47
no switchport
ip address 192.168.1.90 255.255.255.0
!
interface FastEthernet0/48

(SW2)

(SW3)
interface FastEthernet0/47
no switchport
ip address 10.10.10.6 255.255.255.252

log-adjacency-changes
network 10.10.10.0 0.0.0.255 area 0
network 192.168.30.0 0.0.0.255 area 0






From SW2 and SW3, I can ping SW1 on all IPs (192.168.1.90, 10.10.10.1, 10.10.10.5) but I can't ping 192.168.1.1 which is my gateway to the internet.



Not sure what I'm doing wrong.... Any help would be appreciated! Thanks!
