ospf asymmetric Routing

[Ali mosbah Abdo]

Hello all

i have 2 routers connected by 2 links to each other , first link is serial link ( R1----->R2 ) and second link is GRE Tunnel "DMVPN" ( R1---->R2)

and the ospf is enabled on boot links.

the problem that is i have asymmetric routing in R1 we reach subnets behaind R2 through serial linke but R2 prefferd Tunnel Link over Serial Link and replay through  the GRE linke.

i modifed the ospf cost as following:

R1: Serial link , ospf cost 20 , bandwitdh 2000 delay 20000

      Tunnel link , ospf cost 200 , bandowidth 1000 delay 21000

R2: Serial link , ospf cost 20 , bandwitdh 2000 delay 20000

      Tunnel link , ospf cost 200 , bandowidth 1000 delay 21000

But still R2 prefferd the Tunnel linke over serial link.

Please any help
