I am currently having Metro Ethernet Connection from service provider, they have provided us primary and backup link to our branches.
they have provided us last mile copper (fast ethernet) and have two VLANS, for that i have created subinterfaces, did same on branches routers as well.
i want to use primary link (e.g fastethernet 0/0.1, ip 18.104.22.168/30) and when it is up i want all traffic go out through this interface. and incase of any problem backup link ( fastethernet 0/0.2, ip 22.214.171.124/30) will be utilized.
i set ospf cost 10 on fastethernet 0/0.2, but still receiving time outs.
please let me know that does ospf cost works with ethernet subinterfaces?
