Dear All,


I have a two leased lines to a remote location one is 64 kbps and the other is 128 kbps I run ospf with a single area between my HQ router (IBM) and two 1841 in this location, the problem is when I lose the 128 kbps line, the traffic goes to other Line, but when the 128 kbps comes up,the traffic never goes back to it. What could be the problem? and how can I used OSPF to load balance if there is a chance? Can I run HSRP with ospf and how? I've put my config and daigram

I see an addtional network statement on the SE2 router. which network is that?


can you post the following outputs for all the 3 routers

sh ip route, sh ip ospf database


Also how does the 3750 forward the packets? IS it also running OSPF?


I could not understand the need of a hub in ur topology when you could have connected the routers directly to the 2950 switch

Hi Narayan

this acutally a secondary ip address on this interface I have not included it yet, but i will do, I posted ip route an ospf database. 3750 forwards 10.0.0.0 255.0.0.0 packet to 10.2.0.32 staticaly, and it has to vlans vlan 2 10.2.0.0 and vlan 3 10.2.1.0

Hi,


As i see from the configurations, you need to use the Bandwidth command under the serial interface for both router, clockrate is not related to this issue.


second thing, under the ospf proccess in SE2 router,there is no need to command network:

network 1.100.182.0 0.0.0.255 area 0.0.0.0

since no such interface with this IP.


For load balancing,OSPF just do equal load balancing, but you can do it through using same bandwidth parameters, as you have now actually, because the default bandwitdth if not mentioned is T1, 1.542.
