The failures occurring frequently in networks can cause transient routing loops. Each of these transient loops will cause packet losses and may prohibit the Internet server providers from meeting the promised connectivity recovery time and packet loss ratio specified in service level agreements. To enhance failure resiliency without jeopardizing routing stability, and we propose an Imperative-Forwarding -Path-Routing (IFPR) scheme. The proposed approach prepares for failures using an Imperative -Forwarding- Path. This approach doesn't require modifying OSPF/ISIS protocol and can offer full repair coverage for signal link failure. The simulation demonstrates that IFPR can enhance networks' performance and has very little overheads in density networks.
