Connecting 3 routers

[icoltus]

Hello, I have two networks:

One with static routing and one vlan, and the other one with OSPF  dynamic routing and one vlan.

I want to connect the two networks with a router and a copper crossover cable, but I haven't found a way to do it. I heard I have to do a routing redirecting but I don't know how. Any help?

Attached its the networks image.

Hi

Could you please provide more details about the question? You could use dynamic routing protocol like EIGRP or OSPF to interconnect all the routers. Or use static routing but you must include the networks used to interconnect the routers for example:

RSede1 

ip route x.x.x.x <subnet mask> <next hop IP of router 3 / local outgoing interface)  ; Lan 1 in RSe router

ip route y.y.y.y <subnet mask> <next hop IP of router 3 / local outgoing interface)  ; Lan 1 in RSe router

ip route z.z.z.z <subnet mask> <next hop IP of router 3 / local outgoing interface)  ; P2P network between Router 3 and RSe router. 

Now if one the network will be used with static routing and the other one will be used with dynamic routing you must redistribute the static routing into the routing protocol, for example:

Router 3

ip route x.x.x.x <subnet mask> <next hop IP of router RSede1 / local outgoing interface)  ; Lan 1 in RSede1 router.

router eigrp 100 <used to interconnect router 3 and RSe router)

redistribute static.

Sorry I didn't understand completly your answer:

Router three has an ip address of 192.30.0.1 in the port that is connected with Rse, and rse has a ip of 192.30.0.2.

On the other hand, Router three has an ip address of 192.20.0.1 in the port that is connected with RSede1, and RSede1 has a ip of 192.20.0.2.

How would it be with dynamic routing?

Hi @icoltus

 This is pretty simple. What is not working?  Can you share you pkt file?  Just rename it to something.txt and attach it. I can help you with the configuration.

-If I helped you somehow, please, rate it as useful.-

[icoltus]

This is my pkt file

Hi

What is the version of your Packet tracer? I have 7. 

[icoltus]

Version 7 too

[icoltus]

This is my file again, is it not working?

[Julio E. Moisa]

Thank you so much 

For any reason i cannot open it with my packet tracer, could you please zip the file and attach it here?

Thank you

Based on this information you could have: 

Router three has an ip address of 192.30.0.1 in the port that is connected with Rse, and rse has a ip of 192.30.0.2.

On the other hand, Router three has an ip address of 192.20.0.1 in the port that is connected with RSede1, and RSede1 has a ip of 192.20.0.2.

Router 3

router ospf 1

network 192.30.0.1 0.0.0.0 area 0

network 192.20.0.1 0.0.0.0 area 0

Router Sede1

router ospf 1

network 192.20.0.2 0.0.0.0 area 0

<you must include your LAN as well> example
192.168.1.0 0.0.0.255 area 0

Router RSe

router ospf 1

network 192.30.0.2 0.0.0.0 area 0

<you must include your LAN as well> example
192.168.2.0 0.0.0.255 area 0

.zip is also not a valid extension, so this iis the zip file with the extension changed to .txt 

I tried your solution but, I dont know why is not working

[Julio E. Moisa]

Thank you, is possible to paste the configuration of each router here?, also have you configured the ip default gateway on the servers and hosts?

[icoltus]

I change the names of the routers, but is the same topology

[icoltus]

I saved the file again, maybe this one works?

[Julio E. Moisa · Accepted solution]

Thank you please let me try but first this is the configuration you should have:

I suggest remove the current OSPF and configure as following, give few seconds to complete the adjacency. 

Configuration R1 (assume it is router 3)

router ospf 1
log-adjacency-changes
network 192.30.0.1 0.0.0.0 area 0
network 192.20.0.1 0.0.0.0 area 0
network 192.40.0.0 0.0.0.255 area 0

R2 configuration (please check the hostname)

router ospf 1
log-adjacency-changes
network 192.20.0.2 0.0.0.0 area 0

network 10.40.2.0 0.0.1.255 area 0

network 10.40.0.0 0.0.1.255 area 0

network 10.40.4.0 0.0.1.255 area 0

R3 Configuration

Router Rse (please check the hostnames)

router ospf 1
log-adjacency-changes
network 209.165.20.224 0.0.0.31 area 0

network 192.30.0.2 0.0.0.0 area 0

network 192.168.10.0 0.0.0.255 area 0

network 192.168.20.0 0.0.0.255 area 0

netwokr 192.168.30.0 0.0.0.255 area 0
