[j-nsp] OSPF cost : change traffic path

[Rachid DHOU]

Hello Experts,

We have 4 routers : A,B,C and D.

A and B are M7i
C and D are M10i

A connected to C , FE ==> Link 1
B connected to D, FE ==> Link 2

*OSPF and BFD* are runing in each link. but we made a high cost in link 2
(same area). The goal is that link doesn't forwoard traffic.

For your opinion what is the best way to switch traffic from link 1 to Link
2. (i mean best way : the small dowtime and easy operation )

1) In OSPF configuration Reduce cost on Link 2
2) Disable interface on Router A


Don't forget BFD is runing on both links.

Thanks for all your feedbacks.


Kind regards,
Rachid DHOU
