Hi
Could anybody please help me to find why router 3 dosn't show any ospf route in my network? I tried to attach my .pkt file by zipping it but it doesnt not allow.

Router#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, ia - IS-IS inter area
* - candidate default, U - per-user static route, o - ODR
P - periodic downloaded static route
Gateway of last resort is 68.110.171.97 to network 0.0.0.0
68.0.0.0/27 is subnetted, 1 subnets
C 68.110.171.96 is directly connected, FastEthernet0/1
C 192.168.1.0/24 is directly connected, Vlan1
S* 0.0.0.0/0 [1/0] via 68.110.171.97

There is multilayer switch between router 3 and other ospf routers. Does this switch forward multicast traffic? Otherwise, I am afraid router 3 will not see ospf protocol messages from other ospf routers, thus, will not get ospf routes.

Just my 2 cents.

The cable connected to your router 3 is connected to a switch port. Disconnect it and reconnect it to a regular port and set up an ip address with the 255.255.255.0 mask like you had before.

edit: I tried it out and it works fine once you switch the ports. You also have to either change the vlan or change the ip address on the fa 0/0 port on router 0.

Dpjackal89 is right and wrong at the same time. Don't know whether it's packet tracer or not, don't have the gear to check it now, the reason why Router3 and Router0 aren't sharing routers is because their neighbour state is FULL/DROTHER on both sides, they both can't see a designated router on that particular segment, shutting down the Router3 fa 0/2/3 will cause the neighbours to reset, once they reset they will go through the usual process (exchange hellos, elect DR/BR etc).

Hi @All

I had made the mistake of connecting the router with a switch port as Dpjackal89 said above. I changed it with a regular routing port and it works fine.
