Connecting an OSPF network to a RIP Network -- Packet Tracer

Well here's the deal. I have a five router system running RIP. Everything works within the network. I have another five router system running OSPF. Everything works just fine and communication is possible. My problem is when I try to connect the two systems together so that they can communication with each other. I don't know how to configure the border routers.

This is all being done in packet tracer. Anyone know the best way to connect the two routers? I'd like to connect LS Router 5 to Router 8.

Any help is greatly appreciated!

Thank you!

 

hi
On your boarder routers, all you have to do is make a static route to 0.0.0.0 0.0.0.0 to whatever interface is next hop. so on router 8, use ip route 0.0.0.0 0.0.0.0 ip address of interface on router 5 connecting to r8. do the same on both routers.

Then for that route to propagate throughout both routing domains, you will use the default-information originate command.

in your ripv2 domain:
router rip
version 2
default-information originate


in your ospf domain:
router ospf 1
default-information originate

That should do it.

 

Thanks for the reply! This should work over a Serial DCE connection correct? I configured the Router8 static route with the following:

Network 0.0.0.0
Mask 0.0.0.0
Next Hop 172.168.50.1 (Address of Serial Port 2/0 on LS Router 5)

LS Router 5 is configured as follows:

Network 0.0.0.0
Mask 0.0.0.0
Next Hop 192.168.50.1 (Address of Serial Port 2/0 on Router 8)

I then ran the default-information originate command.

I'm still not able to communicate between the two routers though. Am I missing something? Thank you again!

 

Any two connecting interfaces need to be on the same network. So if your 192.168.50.1 interface is directly connected to 172.168.50.1, its not going to work.

Heres a few pieces of info from my running config. First one is on Router 5 in the RIPv2 domain. S1/3 is the connecting interface between R5 and R2 in my picture. To make it simple, i used different /30 subnets in 10.1.1.x throughout the whole network. The concept of using default-information originate is the same, but your network entries in your routing protocols might look different.

Router 5:

interface Serial1/3
ip address 10.1.1.18 255.255.255.252

router rip
version 2
network 10.0.0.0
default-information originate

ip route 0.0.0.0 0.0.0.0 10.1.1.17


Router 2:

interface Serial1/3
ip address 10.1.1.17 255.255.255.252
clock rate 128000

router ospf 1
log-adjacency-changes
network 10.0.0.0 0.255.255.255 area 1
default-information originate

ip route 0.0.0.0 0.0.0.0 10.1.1.18

 

Thanks for the help! I see where I was going wrong. I made the changes to my network and everything works now. Once i had that problem fixed I duplicated the network so I had two autonomous systems. I then connected them together using BGP. Everything works like a charm! Thanks!

 

Hi i have got an assignment which is about connecting a network with RIP V2 with another network with OSPF
there are 2 routers L and S which uses RIPV2 and
they both are connected to another router which is C1
then C1 is connected to 2 other routers C2 and C3 then C2 is connected to 2 networks B and F
and C3 is connected with another 2 routers which is M and D.
I have attached a copy of how the network looks like. I would appreciate if u can let me know by this evening thank you.
