to simplify my pb i want to know if it is possible to prioritize the information of cost compared to the fact of being directed connected.
I have 4 routers connected in "circle" and i use OSPF in this wan (A-B-C-D-A). The 4 routers are connecte with microwave, each connection is an E1 connected to a serial interface. I have pb on the link C-D, that is not stable. So i put a cost of 1000 on this link and pass through others links.
The pb is that, even if i put this cost, all flow between C and D are passing through this link.
Have you got an idea (exept changing OSPF by BGP) to solve this problem, and keep the link C-D only in backup mode.
The different cost on links are auto configurated, and it is 48 when i do a sh ip ospf int.
i am using a single ospf area domain and i increased the cost to 1000 on both interface C and D. but when i make a traceroute it always shows the using of link C-D.
Prasad send a message which talking about PBR, but i don't understand well the PBR. I must make researches to know how it works and if it is possible with 3600 and 2600 routers running 12.1 and 12.3 IOS.
Could you tell me more about it or send me a link ?
