One of the skills that network engineers at the CCNP level need to master is that of route redistribution. Route redistribution is the process of redistributing routing information from one routing protocol into another routing protocol. For example, you could redistribute OSPF routing information into EIGRP or you could redistribute EIGRP routing information into BGP. In other words, you can literally redistribute routing information from any of the routing protocols we have studied thus far into any of the other routing protocols we have studied. One of the more complicated aspects of redistribution deals with the concepts of metric and Administrative Distance (AD) feedback. Your task in this post is to detail the causes for metric and/or AD feedback when performing redistribution and provide examples of how to avoid these issues.
