problem in configuring OSPF

[ashookoul]

Hi,

I am facing a problem in configuring OSPF

Actually in one of our location the LL provider has provided half LL and half RF connectivity in between is a Lunix based convertor which converts LL into RF.The RF part connectivity is configured in Local Lan.Now the problem is how will i configure OSPF in 1751 router . Is there solutin for this as i don't want to configure ospf in convertor as that is placed at unmanged place.The diagram attached with will give the detailed information about the connectivity.

thanks

Hello,

if I understand your question/drawing correctly, you want OSPF connectivity between your 3745 and your 1751 routers without having to configure it on the convertor ? You might want to consider an OSPF tunnel between both routers, the configs would look like this:

hostname 1751

!

interface Loopback0

ip address 10.1.1.1 255.255.255.0

!

interface Tunnel0

ip address 192.168.1.1 255.255.255.0

tunnel source Loopback0

tunnel destination 10.3.3.3

!

interface Serial0

ip address 172.16.15.1 255.255.255.0

encapsulation ppp

!

router ospf 1

network 10.1.1.0 0.0.0.255 area 0

network 192.168.1.0 0.0.0.255 area0

!

ip route 0.0.0.0 0.0.0.0 172.16.15.2

hostname 3745

!

interface Loopback0

ip address 10.3.3.3 255.255.255.0

!

interface Tunnel0

ip address 192.168.1.3 255.255.255.0

tunnel source Loopback0

tunnel destination 10.1.1.1

!

interface Serial1

ip address 172.16.25.3 255.255.255.0

!

router ospf 1

network 10.3.3.0 0.0.0.255 area 0

network 192.168.1.0 0.0.0.255 area 0

!

ip route 0.0.0.0 0.0.0.0 172.16.25.2

Hi

What is the relevence of your 1751 router in your network?Is it acting as a gateway?Are you planning to have 1751 for backup?

I suggest placing the 1751 before the switch.i.e, install an WIC-1ENET (1 ethernet) in your 1751, Create routing between the converter and the router.

This should solve your purpose.

Pls rate helpful posts.
