I want to change metric value of certain networks. I have two routers directly connected via serial ports. One routerA is hoting 172.16.0.0 and 10.0.0.0 network and another routerB is hosting 192.168.0.0 and 172.18.0.0. I want to change metric value of network 172.16.0.0 from 1 to 3 on routerB. Any one know how to do that, plz let me know.
