Re: starting of backup

Hi,

Backup feature can control only main interface. If main interface is down or load on it increases to a configured value , backup interface may become up. Reliability is not the concern of backup command. If you want to use reliability as backup mechanism , the thing only which comes into my mind is to use EIGRP & configure all metric calculation parameters ( K1,K2,K3,K4,K5 ) to make EIGRP take reliability into account . So metric value will change & DDR path will be chosen when main link reliability decreases. When the reliability become good , main link is choosen for forwarding data.

Regards
